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.

While painstakingly finishing the tower of coins, Riza and Will were both surprised when four kids all dressed in martial arts costumes came in from the garden doors. The four lead stars of the upcoming kiddie action series Kung Fu Kids invaded the famous yellow house and attempted to take down the precious tower of coins. But Riza and Will were quick to respond and called Ruben and Gaby for back up. The Big Four then all together protected their tower from the Kung Fu Kids who, because of their small size, managed to run away from the housemates' reach.

However, when the kids found it hard to defeat the grown ups, the Kung Fu Kids tried another tactic. They lured the Big Four into learning the Kung Fu dance choreo, but while the Big Four's attention were diverted, one by one, the kids tried to get close to the tower of coins. Fortunately, the housemates still outsmarted them and prevented them from carrying out their wicked mission. After some kulitans here and there, the Big Four still cooperated in learning the dance, while watching the kids from the corners of their eyes.

Afterwards, Big Brother called the kids into the confession room. The Big Four then took the opportunity to build a barricade using the Coke beach chairs around the tower of coins. Then later, they guarded all the entrance points in the garden, including the glass sliding door, the main gate, and the door to the activity area. From there, the Kung Fu Kids came out one by one and again tried take down the tower of coins.

In spite of the chaotic situation, the housemates seemed to have had a great time having children inside the house. Ruben enjoyed the kids' game, very much used to playing with his son while Riza and Gaby treated them like their nieces and nephews. On the other hand, Will used his height to his advantage in keeping the kids out of the tower's vicinity.

When the kids got tired, the housemates just toured their guests around Kuya's house and offered them some snacks to freshen up. But will the kids still pursue their mission to topple the coin tower?

Tension ran high last night as the whole world waited for the answer to the big question whether Jon would be forced evicted or not, and ultimately, the announcement of the Celebrity Big Four. Fans, ex-housemates and the family of the housemates at risk were filled with mixed emotions when the final hour arrived. Prior to that moment, Jon conveyed his desire to stay until the end during a one-on-one with Big Brother. But just like his prediction, he had to go because he was a "pasaway".

The feeling of being a part of the prestigious feat in PBB came unexpectedly for Gaby, Will, Riza and Ruben. Their joy though was evident as they shared their moment of glory. They even made a toast to commemorate their lucky night as well as their recent ex-housemate Jon. Later, Riza crazily dealt with the fact that she's really "in", much to everyone's amusement. On the other hand, Will claimed that being in the Big Four is enough for him and he doesn't care anymore whatever happens at the Big Dome on Saturday night. He was truly happy not only for himself but also for his close buddy Ruben.

Then the next hours were dedicated to the completion of their latest task, that is, the tower of coins. From the underwater coin insignia that they have formed the other night, Big Brother gave this challenge to them after his quick visit right inside his own abode! Riza was open-mouthed when he told her that he would tour the house to personally inspect what they had accomplished with the emblem. With their urging, Big Brother also tasted their favorite peanut butter sandwich which he prepared on his own. Following that was his deliberate evasion in meeting his residents.

With their usual perseverance in finishing any challenge thrown their way, the tower quickly rose before them. However, they noticed a crack on the table due to the heavy weight of the coins! As such, Gaby and Will devised a strong support comprised with dumbbells and a pan. But as you've seen on Uber and tonight at primetime, the Kung Fu kids arrived this morning to distract the Big Four. Bianca's sudden addition to the group further caused confusion in the house!

Big Brother was able to get rid of the Kung Fu kids but Bianca is still locked in with the housemates. Is she from the "enemy camp" or is she a "friend" of the Big Four?

Bianca sneaked inside the house in a ninja disguise and threatened to ruin the tower of coins, But just when she was about to lay a finger on the tower, Ruben immediately stopped her. Bianca then took off her mask and revealed herself to the celebrity housemates who were playing with the Kung Fu Kids. Everyone was shocked, though, to see that the PBB host was with them inside the house. Bianca asked the housemates and the kids to join her in the living room where the host interviewed our newly proclaimed Big Four.

In a short chit chat with Bianca, the Celebrity Big Four revealed that they were still sad with Jon's forced eviction last night. Will confessed that he sympathizes with the Fil-British housemate given that they both came from the modeling industry and they grew up abroad. Gaby was also affected by Jon's fate, but at the moment, the Racing Goddess chose to look on the bright side, knowing that the English Outcast was evicted because of a violation and not because the people voted him out. On the other hand, the final four are still discussing the contribution that they have decided to give to this edition's final evictee and has yet to set the final amount so Jon will be able to donate to his chosen charity.

But Big Brother cut the interview short and instructed the Kung Fu Kids to go to the storage room and get his gift for Bianca. When the pretty host opened the box, she felt that Kuya was playing a prank on her by giving her a set of towels, some underwear and a lapel mic. How could Kuya trap her two days before the Big Night? But indeed Kuya's serious and is letting her experience the Big Four atmosphere again. What is Bianca's mission?
