Groupers are enemies in Pocketville that are fish. They are very dumb and will always break the fourth wall.
The first encounter was when Skippy was with Liam X looking for a Friendship shard until a big one came and chased them until Liam X pulled out a spear and killed him. The second encounter was when Skippy and Ava where resting by the ocean waching the sun go down untill one came up and said that Skippy should exist. Skippy then clawed him and ate him with Ava. They always seem to be coming in different variations as if they were clones.
