Huckit Crabs are a species of crabs that first appears in New Super Mario Bros. Wii. They wear a red shell and have two yellow feet and only one claw that it uses to throw either sand balls or rocks. Their name is a pun on "hermit crab" (the crab species they resemble) and the term "huck it", referring to their method of attack. They try to hit Mario and his company with their projectiles, which travel in a straight line when thrown. Their rock-throwing technique is very similar to Clawgrip, the crab boss from Super Mario Bros. 2.
In New Super Mario Bros. Wii, Huckit Crabs appear only in World 4-3, where they are found in large quantities. Huckit Crabs are stationary enemies that throw sandballs to the left. Also, by throwing, the force of the throw pushes them back slightly to the right. Huckit Crabs can be defeated the same ways as a common enemy: jumping on its head, freezing them with a Ice Flower or a Penguin Suit, attacking it with a Fire Flower, or by running into it with a Star. The sand balls can also be destroyed, but only by jumping on them, as ice balls and fireballs are ineffective.
