The  was a large red fish that could be found in the waters around Club Penguin Online. It was featured in the minigames Ice Fishing and Aqua Grabber.

In Ice Fishing
Players were able to catch the Mullet in Ice Fishing. They must have had baited the Mullet with a yellow fish at the end of the game. The Mullet would take the bait if the players left the mouse still. Catching the Mullet would have had earned the player 100 coins and the Prize Mullet Stamp.

In Aqua Grabber
Players were also able to catch the Mullet in Aqua Grabber. Mullet was blocking the entrance to the secret area with the crab's treasure, where players could collect the Crab's Treasure Stamp. To catch the Mullet, players had to first catch the worm,Then use the worm to bait Fluffy the Fish. Mullet could then be caught using Fluffy the Fish. Navigating Mullet and dropping it to the top net would earn the player 1,000 coins and the Mullet Capture Stamp. However, it was very difficult to move Mullet as it constantly tried to pull the player. Hitting any walls would have had caused Mullet to escape and swim away.
