A Pocket Chomp is a Chain Chomp inside a small capsule. It is a Bros. Item in Mario & Luigi: Sibling Rivalry. Upon use, the Chain Chomp would break free and chase the Mario Bros. As they are being chased, they jump on the enemy until it is disposed of, if the Action Command is missed, or if the Chain Chomp hits the bro. To deal extra damage, Luigi riding on the chain of the Chain Chomp could use his hammer to deal slight damage. However, if Luigi riding on the Chomp's head uses his hammer, the Chain Chomp only gets angrier and faster. On very rare occasions, when released, the chomp will have a bow on its head. This bow-tied variant is slower than a regular one and doesn't get as angry when hit.
