The Sea Slug is found in underwater in the ocean. Its shadow is small and it moves in a straight line
The Sea Slug can be donated to the museum. Upon doing so, the following text is given by Blathers:
"Although they have no shells, sea slugs are more closely related to spiral shells than anything else. Their vivid colors and patterns and variety of shapes and sizes make them popular with divers. Sea slugs are hermaphrodites, so they are all capable of mating with one another, regardless of gender."
Upon catching the fish, the player will say the following:
"I got a sea slug! What, it thought it could outrun me?"
