|First appearance||"The Deep South" (2ACV12)|
A Colossal-Mouth Bass is a huge bass living in the center of the Atlantic Ocean. When the Planet Express crew went fishing, Bender tied the Diamond-Filament Tether to an umbrella using Hermes' manwich as bait and threw to the water. The food atracted the fish, so it grabbed the manwich, jumped out of the water, over the ship and then pulled everyone to the bottom.
Hermes: [The colossal-mouth bass jumps over the ship] Oh, that's big!
Farnsworth: A colossal-mouth bass!
