"Bloat looks like any regular fish―until he gets mad, that is. When this short-tempered blowfish blows his cool, he puffs up into a spiky ball of rage. When Bloat was little, his big brother used to use his as a football, which just made him madder!"
In the ending of the film, Bloat and the rest of the Tank Gang escape the aquarium exactly as Gill had planned, but Bloat then asks, "Now what?" ending the gang's joy of escape and causing them to worry about how they will get out of their plastic bags.
However, during the credits, the tank fish have escaped their bags somehow. As the credits continue to roll, Bloat is seen having a brief dispute with Gurgle. He then bloats up, and Gill and Gurgle start spiking Bloat around like a volleyball. Then Jacques rolls him along like him rolling a blueberry.
- Like all pufferfish, Bloat sucks water into a compartment in his stomach to inflate, and also like some pufferfish in real life, Bloat often has trouble deflating. Like Bloat is short tempered when he gets agitated or frightened. He also inflates when he burps.
- Bloat was originally voiced by Richard Kind.
- In the post-credit scene of Finding Dory, Bloat's dialogue is archived recording from Finding Nemo due to Brad Garett being busy with other projects
