Big Blue Fish only appeared in Fish Out of Water. He unknowingly chomped Baby Red Fish up in his mouth, mistaking him for prey. But he opened his mouth and let Baby Red Fish out after he said "Abré!". However, soon after that, he and Baby Red Fish both got chomped up by a Giant Green Fish who also mistook them for prey. He eventually opened his mouth after they both said "Abré!" together.

It is unknown who voiced him as it was not listed in the credits.
