|Attack||Dangerous on contact|
|Game(s)||Ninja (Mega Mash)|
Crab bots have a blue square-shaped body, with two blue claws on both sides. A back metal part connects the head with the body. The head is in the same shape as the body, and has a single light red robotic lens for an eye, as well as some other small lights on its face. Atop its head is two antennae, with a red light on the end.
Positioned on the ground and only moving back and forth in a horizontal direction, crab bots do not attack the ninja in any matter except hurting him on contact. They often occupy the same areas amongst each other. Attacking the crab bots may be difficult for a player, considering that the ninja's ninja star can only shoot diagonally and the crab bots only remain on the floor of each level they are on.
