The celebrity housemates could only sigh when the Kung Fu Kids accomplished their mission to sabotage the coin tower that they have tediously rebuilt over and over again. With that done, the hyper-active children spent the remaining hours playing around with them until Bianca swapped places with the bulilits. Unknown to the former boarder of Kuya, her "return pass" to the outside world depended on whether the celebrity Big Four can create a tower which stands three dangkal-long.

It was an attainable feat but they were worried about possible intruders who can attack them anytime. Big Brother's plan of destruction came in full swing right after he tricked his residents into changing their lapel batteries. That was when the unknown ninjas entered in a rush just to frighten them with the basketballs they have hurled near the delicate structure on the plastic table. The four instantly prepared for the next attack as they were barraged with more distractions. And in a split second, they failed to see the ninja who made a perfect aimed for the "target". Though giving up was far from their thoughts, they were simply too tired to give it another try that evening. But at least, they managed to give Bianca her freedom earlier in Uber.

Aside from their continuous efforts for their difficult construction project, each of the Big Four presented their gimmick in promoting their bet for the Big Win. First off was Riza who sported a fisherman's attire to campaign for herself through her vision of environmental progress. Ruben advertised Gaby's admirable talents while wearing a car-racer's suit. On the other hand, both Will and Gaby predictably asked the viewers to choose the comedian from Davao for he truly deserves to land the much-coveted first spot.
