Pinoy Big Brother: Unlimited was a Philippine reality show based on the Big Brother franchise.
Below is a chronology of events that occurred over the course of the season from October 29, 2011, to March 31, 2012. This article also lists voluntary and temporary exits, entrances of houseguests, visitors, new housemates, and other events that affected the housemates' lives inside the House. October 29, 2011 is considered Day 1.
Week 1 Day 1: Thirteen official housemates crawled through a hole into the Big Brother house. One sub-official housemate was a mole. They were set to live in the slums, similar to how 15 million Filipinos live. Paco, Slater and Luz were asked in the confession room to choose an unlimited supply of one of the necessities of water, food and clothes. After deliberating and considering the others, they chose food. Day 2: Big Brother gave the housemates' first weekly task. The first challenge was to create useful things from scrap, which the housemates won. The second was for six singers to cumulatively score 540 on the Aegis ballad Luha (Tears) in Karaoke. Jaz, Kim, Pamu, Kigoy, Kevin, and Carlo volunteered to sing and won. Big Brother then asked the housemates to tell scary stories. Kevin had the scariest story and won unlimited water. Carlo was then informed of his impossible tasks. He successfully retrieved one item of clothing from Divine, Kevin, and Kigoy. Day 3: Big Brother scared the housemates at night with frightening noises and people in costumes. Luz, Tin, Seichang and Biggel successfully erased the word UNLIMITED painted on a wooden bench in the third challenge using only sandpaper strapped on different parts of their bodies. Carlo woke up in the early hours to try puncturing the housemates' water tank without being seen. Since his nails weren't sharp enough, he was forced to carefully tip it over and let the tank drain itself. Kigoy and Luz argued briefly over cooking rice. The housemates had to shoot basketballs backwards in the fourth challenge and score 21 out of 40. Divine was the lone scorer with one point. Big Brother gave the housemates a second chance to shoot, offering one scoop of water from a normal shot while a full container if the housemate successfully scored backwards—but cannot share the water. Only Jaz scored backwards and took a bath with the water she won. Day 4: Kigoy and Carlo had to fan for 24 hours continuously in the fifth challenge, which the housemates lost. Day 5: The housemates designed a toy house using nails in the sixth challenge. Carlo and Luz then had to remove the nails, which they did successfully. Day 6: In the seventh challenge, the housemates had to ride one round on a pedicab missing the sidecar's wheel. The housemates were unsuccessful and lost their weekly task. Big Brother summoned Carlo to the Confession Room and gave him one hour to finally complete the last impossible task: finding the henna tattoos. He only got three tattoos correct, but Kigoy's was incorrect. Seeing Carlo's failure, Big Brother outed Carlo to the housemates by summoning him to the confession room as the unofficial housemate. Carlo sought a second chance, prompting Big Brother to let the true housemates discuss whether to keep him—something that caused division. Day 7: Big Brother asked the housemates to do a rap version of "Pinoy Ako" with Biggel doing the beatbox. Each housemate was also tasked to put one item of clothing in the confession room.
Week 2 Day 8: Carlo officially became a housemate with only one of the thirteen housemates rejecting him. At the confession room, he had to pick six rattan boxes containing one item of clothing each from the other 13 housemates. The clothes belonged to Paco, Pamu, Kevin, Jaz, Seichang, and Kim, who first occupied the second House (Industrial House). Roy was later revealed to the audience as the lone dissenter. Meanwhile, 15 new housemates entered the House in two teams. Jerico, Diane, Anatoly, Casey, Wendy, Joya, and Eting were made to dip into a pool of dirty water and assigned as street urchins and choose a housemate to pair up with. They could only communicate with their partner non-verbally (which is a special task for new housemates). Big Brother also tasked Slater to make his housemates believe that he fell for Joya at first sight. Day 9: At the Industrial House, Naprey was the first of the second batch to be present in that house and had to cook breakfast while the original six slept. Later, the six original housemates were summoned to the confession room to meet their new housemates. Kim was shocked that her boyfriend Mark would also be a housemate, but both were later ordered to keep their relationship secret or risk nomination. The original six housemates were told to pretend to the new housemates that they all entered at the same time. Later the housemates had to walk while crouched, the same way Naprey walks when not on his wheelchair. The success of the task resulted in Naprey being allowed to use his wheelchair. At the Slums, Eting, Joya, and Wendy decided to have unlimited food at the expense of having limited water and clothing. The Slum housemates then talked about the stories behind their heirlooms. Unknown to everyone, this was just the first part of Casey's weekly task. Day 10: During the wee hours in the Slums, Casey performed the dance part of her weekly task as everybody slept. At the Industrial House, Kim and Mark were allowed to spend time together while their fellow housemates slept. In the morning, aspects of Japanese culture arrived in the Industrial House, such as the housemates sitting on the floor while eating breakfast with chopsticks. The weekly task note was even written in Japanese (and had to be translated by Seichang), and the housemates also had to wrest their materials from two sumo wrestlers. Later, the male housemates dressed and acted like geishas. Back in the Slums, Kigoy's remark about cigarette smoking almost caused an argument between him, Diane, and Roy, only to be quelled by the others. Casey took opportunity of this event to recruit Joya for her secret task, claiming she saw an invisible black aura around Kigoy. In turn, Joya tried to convince Roy to join her and Casey. Later, several housemates won several items from the sari-sari store by flipping large disks, hoping they turn up the same color. Carlo and Biggel offered to wear high-heels for 24 hours continuously in exchange for Big Brother giving Kigoy a fresh pair of bakya slippers since his original pair couldn't be repaired. Kigoy also caught the group's ire because he had stolen kisses from Diane. Both of them later had a serious conversation in which Kigoy was made to understand that he has to learn to be considerate of others' thoughts and feelings. Regarding Casey's secret task, Roy finally joined the nightly ritual. Day 11: At the Industrial House, the women dressed themselves as sumo wrestlers in padded suits. In the sumo competition that ensued, Pamu remained undefeated against the other girls. When facing the sumo wrestlers from the day previous, the girls again won, both in two-on-one handicap matches and in a one-on-one match between Pamu and one of the wrestlers. Seichang refereed the matches. They were rewarded with a shiatsu massage while wearing blindfolds. The girl housemates were surprised to see the male housemates doing the work after taking off their blindfolds, which irked Kim because Paco chose to massage her when Mark would have jumped at the opportunity as her boyfriend. At the Slums, Big Brother assigned the housemates to do a two-minute pole dancing routine without their feet touching the floor in exchange for a special lifestyle package (which later turned out to be an unlimited supply of water and ice cream). Slater tasked Carlo to create three paper roses for Joya and Diane to deliver them to her. In Casey's secret task, Anatoly and Slater joined her group, although Slater had his doubts. Coincidentally, after the three finished their "ritual" along with Roy and Joya, Kigoy coughed while sleeping upon being touched by Casey, bringing her fears that her fabrication was becoming real. Day 12: In the Slums, as the last part of Casey's secret task, Big Brother specifically told her to recruit Luz and convince the latter to lift her up during the ritual. It was already made harder by the fact that the persons she recruited began to doubt her and the fact that her actions and remarks already made the rock more like a supernatural object than the lucky charm Big Brother wanted it to appear. The stress of Slater's task later forces him to quit, resulting in Big Brother giving him an automatic nomination. Day 13: At the Industrial House, the housemates donned school uniforms for a Japanese-language course with Seichang and Erica as instructors. They also ate sushi off a sumo wrestler lying in the living room. At the Slums, Joya was finally informed of Slater's secret task and the consequence of him quitting it. She was then given her own secret task of inviting Slater to a dinner date, which she successfully accomplished. The date would have been the final part of Slater's task to test its success. Day 14: Casey successfully completed her secret task despite Wendy earlier asking her housemates about reportedly seeing some housemates doing the ritual. The Slum housemates were left overjoyed that their budget relied on the success of her weekly task. At the Industrial House, Seichang confessed to Big Brother that he likes Jaz, which prompted Big Brother to assign him with giving her three compliments. The Industrial House denizens' origami task took a different turn—they had a short time to redo the origami designs they did earlier from memory and use large sheets of paper for them, with next week's budget at stake.
Week 3 Day 15: Big Brother meted punishments on several housemates at the Industrial House. Seichang was forced to communicate using a sock puppet because of misuse of the lapel microphone. For failure to respond to the wake-up call for a third time, Pamu strapped herself onto a gurney and was told not to move until told. Lordwin and Unad were made to wear two jackets conjoined back-to-back due to their use of hand signals. The housemates in both houses also watched the pilot episode of the upcoming show Angelito: Batang Ama. The stars of the show, Charee Pineda and JM De Guzman visited the Houses, with Charee having a video chat with the boys of the Industrial House from inside the confession room and Eting and Wendy meeting JM blindfolded by saying the name "Angelito" correctly at the Slums. Kim and Mark also came closer to being unmasked as a couple. At night, the Slums housemates were told that their pole dancing routines were a success, enabling them to have an unlimited supply of clean water. A new batch of housemates, dubbed the 3Gs (3 Gorgeous Girls) and the Power Strangers, were inserted into the Resort and the Industrial House respectively. Because of Slater's failure in the secret task, he was assigned to convince his fellow male housemates to accept the 3Gs as official housemates, even if it would be at the expense of one of the female housemates. If even one of them would refuse, he would have to either choose which female housemate has to leave or face a forced eviction. Inside the confession room, the 3Gs analyzed each of the Slums male housemates as they took a bath, then Slater also got to see the 3Gs for the first time.
