Pool

At first glance, Pool is nearly identical to his previous iteration, starting out as dead. However, it's shown that he's acting the role of Dead Pool, meaning he isn't actually dead and is simply doing a bit. He appears to be crafty and dedicated to his role, not bothering to even speak, open his eyes, or even SHOWER until he's in immediate danger, and he will only move when nobody's looking. He can also somehow teleport instantaneously, as shown in BLINDED, and used this ability to take Jelly Bean and Candy to the finish line alongside him and win the challenge, also somehow filling himself up with hot water. He seems to also be able to emote by spawning a fly out of his mouth.

Aside from this, he has no discernible personality that isn't related to his acting career, since he's been so focused on it. One could assume that he doesn't completely prioritize this "role" over anything, since he opens his eyes in shock while flying towards Limbo Island, but this doesn't really mean anything important as any reasonable person would've done the same thing.
