Crabs are weak enemies found in Oceans. They walk along the bottom and occasionally jump, making them a little bit harder to hit with a ranged attack. They may also walk on land, and whether or not they're in water has absolutely no effect on their behavior. A player can get them to travel across the entire screen.
- Crabs can also be spawned with a Crab Statue. Such crabs will drop no money, but are a good source of the Crab Banner.
- The Crabs spawned by a Crab Statue can furthermore be used to make a so-called "Crab Engine".
- Crabs are very light creatures and suffer from considerable knockback. This can make fighting them a bit irritating, as players have to continually run after them.
