Balloon then refers to Taco as "the useless one". However, he uses her as an advantage and kicks her up in the lemon tree to get there lemons. Balloon then became angry when Bomb said that she can only speak French and some other words, stating that they're so doomed. When Pickle tells Balloon to be nicer to Taco, Balloon then cusses at Taco so Pickle kicks Balloon away. Balloon then lands in the tree but can't see any lemons so he accuses the tree of being "rigged". When there is only 20 seconds left and Team Chicken Leg have pretty much lost Balloon blames Taco and kicks her.

He spoke without recycled lines for the first time in years, shocking all the old contestants. Salt was suprised that he talked, so Balloon explained since he joined the season, he might as well started saying actual stuff again. Salt rejected this and reminded Balloon that no one likes him. Balloon said it's not true right before Toilet hopped up to him and repeated that nobody likes him. He replies with his signature quote: "Oh, come on!" In both challenges, Paintbrush popped him before anything else happened.In Marsh on Mars, Balloon said he want to help, but Cheesy said he was not very "pop-ular." Balloon admitted he was a bit bossy, but not evil, so Suitcase was glad Balloon could help on the rocket. Nickel was surprised that Balloon was actually helping and not annoying people.

In Everything's A-OJ, Balloon seems excited by the prospect of returning to Hotel OJ. Knife reminds him that he probably won't be welcome since he vandalized it with spray paint the last time he was there. Balloon is under the impression that in the long time since, both he and Knife have changed. Knife argues that just because he may feel like a different person mentally, the people in the hotel won't see that and just view him the way they always did. Pickle insults Balloon's intelligence, causing Balloon to snap, stating that he at least knew Taco was "nothing but trouble."
