Shark

Not to be confused with the athletic team.

Sharks are part of the Club Penguin wildlife. They appear in the mini-games, Ice Fishing, Catchin' Waves, Jet Pack Adventure, Hydro Hopper, and Puffle Rescue.

Behavior

Sharks are quite aggressive, and will attack penguins, worms, crabs and puffles if they get close enough.
