Hop-Chops

Hop-Chops are uncommon enemies that first appear in Super Mario 3D World. They are sentient green springboards with a square head, red eyes, and sharp teeth. These enemies usually appear in groups of three or more, and reside in areas where a springboard is required for objects, like Green Stars.

Super Mario 3D World
In Super Mario 3D World, when players approach a group of Hop-Chops, they will begin to bounce towards them. Hop-Chops can be defeated by jumping on top of them, hitting them with projectiles, or swiping them with the Tanooki tail or Cat claws. Defeating a Hop-Chops sometimes turns it into a springboard which the player can carry and use, and is often used as a puzzle element in which the player has to figure out which Hop-Chops among the group will turn into a springboard upon defeat, rather than just falling apart into pieces. If a Hop-Chops does not break apart after being attacked, a sound will play signaling that the player has found the 'correct' one.

As springboards, Hop-Chops can be picked up, carried, and thrown. Much like Brolders, Hop-Chops that do not break upon being hit will come back to life if they are not attacked after a certain period of time. Also like Brolders, if a Hop-Chops turns back to normal while in a player's hands, that player will take damage before dropping them.

Super Mario Maker 2
Hop-Chops reappear as enemies that can be placed in Super Mario Maker 2 stages. In this game, they can be jumped on for a higher bounce, acting like Trampolines.
