The Flatworm is found in underwater in the ocean. Its shadow is small and it moves in a straight line.
The Flatworm can be donated to the museum. Upon doing so, the following text is given by Blathers:
"Flatworms are flat creatures, and while some types look like sea slugs, they have little else in common. Some types are venomous and produce a poison similar to the kind blowfish are famous for. Flatworms are hermaphrodites and mate by fighting to determine the loser, who then bears the eggs."
Upon catching the fish, the player will say the following:
"I got a flatworm! Why's it so flat? Steamroller?"
