Joining the first eight housemates introduced in season two, episode one, Gaby enters the house riding a "twister bike" (basically a child's trike) along a ramp that leads to the pool.

Mcoy and Zara entered the House in two different instances. Mcoy sang Pinoy Ako directly inside the confession room and later entered the House. Later, Zara was escorted into the House by Baron. Will accidentally fell into the pool while still wearing his lapel microphone. As a result, Big Brother gave Will a handheld microphone in place of his then-wet lapel microphone.

Mariel brought Jon into the House, but Big Brother trapped her inside the House. She was later made into a "celebrity house guest." Ethel was welcomed with a small party organized by Big Brother. Ruben, being in the same profession as Ethel, was tasked to host the party.

Marylaine, Will, and Mariel became the first three housemates to use the punishment room for various offenses. Will and Mariel peeled a bowl of lanzones using their mouths, and Marylaine shed coats of squash seeds.

Will finally had his lapel microphone returned to him, but he had to get past cockroaches and other insects to get it. Marylaine and Jen were put in the punishment room for a violation Jen committed. Their bickering continued there while installing train tracks used in the weekly task. The entire task took overnight, but the two eventually reconciled.

The first HOH competition was held wherein the housemates wore giant "hands" and played a game similar the Japanese game of karuta using colors. Ethel won in that game.

Donnie and Marylaine finally have several of their clothes after Gaby and Victor packed some of their things just to make it happen.

Gaby momentarily left the House to compete in a Formula Three race in the Subic International Speedway. She finish first in the second heat of the competition. Main primetime host Toni became the new houseguest.

The second HOH competition was held, involving children's trikes. Riza, Ruben, and Will won in each of the three preliminary heats, with Riza winning the final round and the title of Head of Household.

Mcoy, Victor, and Riza temporarily left the House to help embalm the body of a man who had been dead for a month due to a heart attack and whose family had no money for a proper embalming, let alone a decent funeral. Inside of the House during the absence of the trio, the other housemates also did Halloween-related tasks also to help the said man's family.

Baron smashed a pane of the living room table with his foot. The table was taken out to be repaired. Later, after the housemates partied with Bea Alonzo and John Lloyd Cruz in a black-attire party, they saw that every other table in the House was gone. In particular, the long dining table was replaced with two panes of glass on which they would eat, with some housemates acting as one pane's "table legs."

Toni was told that she could leave the House. But before she left, she wrote and recited a poem to the housemates, saying thank you to them.

Yayo was taken to the hospital due to high blood pressure as recommended by the doctor. She returned to the house the next day. Ethel accidentally broke a very small part of the chandelier in the men's bedroom while tossing throw pillows with several of the housemates. As a result, all seven male housemates were incarcerated in the punishment room while Big Brother decided on the punishment to be given to them.

Baron, Donald, Will, and Ruben participated in a task of balancing a number of plastic goblets in a failed attempt to salvage their weekly budget. Later, the housemates came to the aid of Peggy, the pig they were nursing as part of their Season-Long Task, as the sow had given birth to a total of ten piglets, nine alive and one stillborn.

The housemates christened Peggy's nine live piglets, even giving them names such as "Posh," "Sweet," and "B-Boy" to mention a few. Later, Gaby was given time to decide whether she would make an exit to attend a seminar in the United States or not.

The third HOH competition was held involving human bowling pins and a swinging bowling ball. The Geisler brothers, represented by Donald, won the title of HOH. Later, Gaby ultimately decided to make the exit and attend the said seminar. Furthermore, Ethel, with the help of Ruben, finished a new table using giant pick up sticks from an earlier game. Big Brother not only lauded the new table; he also made it the new living room center table to replace the glass one smashed by Baron. Along with the new table was the return of the remaining good tables in the House.

Ethel requested a home pregnancy test from Big Brother to confirm this possibility. The next day, when she had her test, it came out negative.

On the wee hours, Jon, who was deeply distraught over the news of his aunt's death, temporarily left the House on the wee hours of Day 26 to visit his aunt's funeral, personally offer the flower arrangement he helped Ethel make, and pay his last respects to her. It was already morning when he returned to the House.

Victor, Mcoy, Riza, Gaby, and Megan picked the short straws and were sent by Big Brother to the Cebu Provincial Detention and Rehabilitation Center to dance The Breakfast Club's Rico Mambo with its inmates. The five returned to the House in the afternoon. Later, Jon, while blindfolded, had a 100-second encounter with his mother.

Ethel threatened to leave the House without Big Brother's consent, even toying with a small straight razor. Fearing for her life, the other housemates stopped her and urged her to speak with Big Brother.

The fourth HOH competition was held, involving the housemates hanging onto punching bags for as long as they could without touching the ground. Victor, Jon, and Will were the only ones left hanging after fifteen minutes. Will would eventually become the winner of title.

Big Brother started to mete out punishments on housemates who committed violations.

The Geislers, Jon, and Riza were "nominated for eviction." Unbeknownst to the housemates, the nomination round was really just a mock one.

A mock eviction night was held wherein the Geisler brothers were "evicted" from the House. Upon exit, they were led by Toni to an empty Eviction Hall and from there they were brought back to the confession room. At the confession room, the brothers found out that the whole process was a hoax because Big Brother wanted to tell them that he had decided to abolish their 2-in-1 connection (which was already planned by Big Brother).

After having a 100-second encounter with their mother, Baron decided that Donald would be the one who should continue his stay in the House. Baron did not leave completely as viewers were made to decide through a 24-hour viewer poll on whether Baron's stay should be extended.

On the wee hours, Mcoy and Ethel decided to make a voluntary exit and soon after left the House after conflicts involving the weekly task fumed the two. Accusations of plagiarism caused conflicts between Mcoy and Big Brother while Ethel went with Mcoy because of her already existent plans to leave. Later Baron found out that he could return to the House, as 91.69% of those who voted in the viewer poll agreed to have him back inside.

In an episode of Über wherein Mcoy and Ethel were guests, Big Brother subsequently apologized to Mcoy about any misunderstanding they had during that time, to which Mcoy accepted.

After nominations were announced, Angel Locsin entered the House dressed as a sniper, shooting orange paintball pellets at the unarmed male housemates.

Angel, Mariel and six of the housemates went out of the House to a firing range to learn and test their use of a .45 caliber pistol. Baron and Yayo were left behind in the House as part of their punishment; Baron broke another glass goblet days before while Yayo accidentally chipped a drinking glass. The two spent the time cleaning the House and making food for the housemates. It was during their final chore-washing Big Brother's car-that they found out that Gaby had returned. The other housemates also greeted Gaby upon their return.

The fifth HOH competition was held. It involved the housemates crossing a beam over the swimming pool in the shortest time after being spun ten times over a rotating platform. Will was declared the winner. But the next day, citing Mariel's observation and a review of the game, Big Brother decided to transfer the title to Baron.

Gladys entered the House and after some introductions and greetings, she sang karaoke with them.

Victor and Riza temporarily left the House to engage in a wakeboarding task in Batangas in which Victor won. The two returned to the house later in the afternoon. Later, Big Brother relayed to the housemates some brief reports (with some fabrications inserted) relating to the stand-off at the Manila Peninsula Hotel.

International R&B artist Akon visited the House after having a concert the previous night despite the curfew after the Manila Peninsula siege. Mariel, Gladys, Donnie, Jon, and Victor, who were winners in an earlier charades game, personally greeted the artist inside the confession room for 100 seconds. To be fair, Big Brother let the rest of the Housemates meet Akon, but only for ten seconds. Akon spent a short time inside the House because of his tight schedule.

Mariel was finally told by Big Brother that she could make her postponed exit. She let her say her goodbyes to the housemates and left the House area's front doors before her 100-second period expired. After a few minutes and a quick change of wardrobe, Mariel returned to her hosting duties.

The sixth HOH competition was held wherein winners of seven mini-games must select a fellow housemate to leave a boat floating on the swimming pool. Mini-games played include picking cards, flying paper airplanes, drinking distasteful food, and blowing whistles among others. After the mini-games, Jon and Donald were the ones left on the boat, but the decision who would be the HOH rested on the other housemates. Jon got the nod of four out of the seven housemates, earning him the title.

Peggy, the pig the housemates were tending to as part of their Season-Long Task, was given away to her new owners. The housemates who were saddened by the pig's departure, would still continue to take care of Peggy's piglets.

While chasing her piglet Porkchop, Gaby accidentally jumped into the swimming pool not realizing she was still wearing her lapel microphone. As the lapel mic was broken beyond repair, she had to share with Donald's own microphone.

Big Brother furthered Gaby's punishment by spending the night the piglet pen and communicate with the housemates using semaphore flags, as suggested by Jon. Donald, being the cause of her further violations, later decided to join her so her punishment would be less harsh for her. Her punishment ended the next day.

Ethel visited the House in the wee hours of the morning and talked with Big Brother. Citing the changes among the people she knew and having missed the housemates, she expressed her willingness to return. Big Brother told her that he would think it over, especially her time spent in the House the first time. His decision, he told her, would be known in the "appointed time." Later in the evening, Ruben finally made his long delayed marriage proposal to his partner, the mother of his three children, who responded by telling him that she would think it over. Much later, Mariel, having missed the housemates, accepted Big Brother's invitation to be in the House once again.

Gladys told Big Sister (Mariel) her intention to leave, even deciding not to participate in "Olym-pigs." Big Sister, on a loss of what to do, told Gladys to hold on until Big Brother's return. But the advice only made Gladys's plea to let her make her exit stronger. Meanwhile, Ruben personally reiterated his proposal to his partner; this time it was accepted. The acceptance was shown to the others two weeks later.

Gladys left the house after slipping into depression for the last two days. In contrast, Big Sister convinced Gaby to stay. The latter already mentioned to Big Brother plans for a second voluntary exit days before.

Ethel emerged from the confession room together with Jan and Vier. Mariel and the housemates gathered around to welcome her back.

During a cocktail "beach party," Baron became intoxicated, flirting with several female housemates and unintentionally insulting Big Brother. He was accompanied by the other male housemates in the secret room to help him sober up.

Popular character Barney T. Dinosaur visited the housemates and danced with them for a short time.

The housemates sold their paintings of their piglets to raise P20,000 for charity. This was made as an alternative to selling their piglets to siblings "Lydia," "Tomas," and "Mila" (names associated with the roasted pig business) in exchange for the same amount. Later, noted plastic surgeon and beauty specialist Vicki Belo visited the housemates. She gave them advice on skin care. The housemates were also treated to a full body treatment by workers of her clinic.

After burying her mother, Yayo expressed her decision to return to the House, creating a complicated situation with only two weeks left in the show's extended run. Endemol created four conditions for Yayo's return, one of the first three being that one of the six Housemates still in the House should voluntarily surrender his/her stint. Gaby readily stated her intention to end her second stint.

Big Brother signaled the end of the Season-Long Task and instructed the housemates to say goodbye to their piglets, who would rejoin their mother at a zoo/animal farm in Tagaytay. Later, Yayo was allowed to leave the secret room and be with the housemates once again.

The housemate had their Christmas Eve dinner. They agreed to exchange their menu for their dinner with food prepared by a poor community for their dinner.

In the wee hours, Baron broke a promise he made to Big Brother when he once again became drunk and made offensive gestures in the process. In the morning, Zara, Megan, Victor, Jen, Marylaine, Donald, and Mcoy each visited the remaining housemates for a hundred seconds to personally greet them Merry Christmas. Later, Ruben had his Christmas gift: witnessing his mother, her sister, and her mother reunited inside the House for the first time since even before he was born.

Baron was told that he had been forced out the House as a consequence of his second drunken stupor during the wee hours of Christmas which resulted in various violations, unintentional insults to Big Brother, and later, Gaby's ire. Donald returned to the House to fetch him.

Ruben and his partner were finally married at a nearby church. Later, Mariel and Ethel made their final exits. In the first of two tests set by Big Brother shortly afterwards, none of the five willed to answer which of them does not deserve to be in the "Big Four." In the second test, Ruben was unanimously voted by the others as the one deserving to be the "Big Winner" of the second Celebrity Edition.

Somehow pressured by the various signals and videos about what they did the night before and Big Brother's unwillingness to talk, the five housemates decided to answer which of them do not deserve to be in the "Big Four." But all five gained the X-medals, forcing Jon to "nominate" the two females for eviction. Unfortunately, a remark by Jon before nominations implied that something was afoot and their problems with Big Brother did not end at the moment of the "live nomination."

Jon finally admitted to that his remark somehow influenced the voting the night before. In fact, to seemingly support this, Ruben and Gaby confessed that it was not their intention to nominate their selections (Ruben chose Will; Gaby chose Ruben) rather than Riza. Big Brother reminded the five of following rules, but decided to hold out Jon's consequence to a later time in order not to spoil the revelry of New Year's Eve.

As consulted by Endemol, it was decided that regardless of his standing in the open voting, Jon would be given the forced eviction because of his violation of rules due to the implied influence of his remark during the "nomination" round three days before.

Bianca, together with several actors from the upcoming show Kung Fu Kids, entered the House to interview the "Big Four." It was only during the course of the interview that she had found out that she became a house guest.

After some talk with the housemates and helping them with their coin tower, Bianca was told that she could leave. Immediately after her departure, she hosted the last episode of Über for the season.
