|Appeared||Around Club Penguin Island|
Crabs (Clubpenguinus crabus) are one of the creatures that inhabits Club Penguin Island, and are seen quite commonly. They can be seen in the Underground Pool, the games Ice Fishing and Aqua Grabber, along with the Secret Missions 5-11. The most notable of these are Klutzy and Klepto. The crabs in the game Ice Fishing crawl upside down on the ice, while in the water. They try to steal your fishing bait (a worm), by cutting your fishing line.
Aqua Grabber Crab
In Aqua Grabber's level Soda Seas, there is a secret worm that can be obtained. It can be used to capture Fluffy the Fish and then Fluffy the Fish can be taken to catch a Mullet. The Mullet is released and there is a path where the mullet was. You can go through it and down to find a crab and a large pile of coins that can be picked up. The crab will also try to take the treasure. If you let the crab get all the treasure, he will give you the rare treasure.

Klutzy is a villainous crab and partner in crime of Herbert P. Bear. He was first seen during Secret of the Fur and has made recurring appearances throughout many of Club Penguin parties and events. Namely: Operation: Puffle and various missions.
Ice Fishing Crabs
On the fourth stage of Ice Fishing, Crabs crawl on the "underside" of the ice and creep towards the fishing line to try to cut the line off, so that you lose your bait. They will wait for a few seconds before extending out the claw, so you have time to reel in your rod.
- Main article: Clawdius
A scrapped crab villain, which only made a few cameos.
- Main article: Klepto
Klepto appears in Puffle Launch as a boss in every 6 levels. It steals the O-Berries in the starter video, causing the game to happen. It also uses an old Aqua Grabber 3000 with a jet pack. It usually attacks your puffles and it is placed near the finish ring. To defeat it, just hit it hard in the bottom and it will fly away until it explodes. Dot also suggested that this could be Klutzy, but was proven false. In the Top Trumps - Club Penguin set, the crab's name was revealed to be Klepto, who could be related to Klutzy.
- Main article: Pirate Crabs
Pirate Crabs were crabs that had boarded Rockhopper's ship after habituating Swashbuckler Trading Post, and are currently sailing to Club Penguin Island on the aforementioned pirate's ship. After traveling several weeks on the ship, the pirate crabs eventually came in to close proximity of Club Penguin Island. As a result, they crashed the second Migrator into an unknown obstacle and then proceeded to first invade and then burying Rockhopper's treasure with the notion of annoying the pirate; then presumably stealing the luxuries for themselves.
