Bloat

Bloat is a puffer fish in Finding Nemo. He is voiced by Brad Garrett.

Personality
Bloat is a puffer fish who lives in Philip Sherman's office tack. When he gets scared or agitated, he bloats up, and then one of the other fish has to deflate him. Bloat is from "Bob's Fish Mart."

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.
