Day 50. Prior to their entry, two housemates, in separate instances, were first chosen by the teen finalists of

The first group who entered the House were Jyo, Roger and Dawn; they were followed by Charlhone, Mikee and Margo. The said housemates entered an almost empty House of which they had carried over from the teen housemates wherein, upon the latter group's last week, the furniture and other things were taken away by
ninjas. Instructed by Enchong Dee, their first task was to keep the activity door open and get the lost 65 furniture and place it back inside the House perfectly as based from the House's floor plan. They were only given one hour to finish the task. They were successful in getting all 65 furnitures; however, they failed to place 3 of them in their right positions. On
Day 51, the last six housemates, Richard, Krizia, Jessica, James, Miho, and Philip, entered the House. The first five were tasked to play as babies and that the first batch of housemates had to feed and put them to sleep before they can act back normally as adults. Philip, the last to enter, was permitted to bring his son inside the House; his wife was also allowed to enter the House as a special privilege to take care of their baby. In a surprising twist, on
Day 52, the housemates were told that the nominations would take place later that day and that they were only allowed to nominate one person; from all 12 of them, Miho was nominated with three points. In the evening, Enchong exited the House secretly.

Big Yanig. Housemates won the weekly task with the net total amount of P93,385.25, which was earned from the two-day Food Fest. Dawn, Margo, Miho and Richard earned P47,491 while Charlhone, Krizia, Mikee and Roger earned P45,894.25, which gave Dawn, Margo, Miho and Richard immunity from nomination and Charlhone, Krizia, Mikee and Roger an automatic nomination. Because of the new twist, Charlhone, Krizia, Mikee and Roger will face the Ligtask challenge as a group. If Charlhone, Krizia, Mikee and Roger fail the task, only one of them will be saved from eviction at the end of the week; however, if they win, only one of them will be evicted. They were originally given 73 minutes and 7 seconds to win the challenge, but Big Brother gave the safe housemates a task to lengthen the given time by forming a circle and each fusing half of a cylinder, containing two balls, on both hands. The timer stops at the last pair breaking the fusion. 56 minutes and 29 seconds were added, with a total of 129 minutes and 34 seconds to win the task. They failed at accomplishing the task. On the same day, the safe housemates were asked to pick one housemate who they want to save. On
Day 79, the eviction process began and the safe housemates were tasked to put on the
Ligtas medallion on their chosen housemate. Roger got the most votes with two medallions, leaving Charlhone, Krizia, and Mikee, with one medallion, to be evicted from the House. On
