Mecha-Chomp

Mecha-Chomps are Chain Chomp-like enemies that appear Mario & Luigi: Superstar Saga. They are found at Woohoo Hooniversity, where they only appear during battles with Laser Snifits in the basement. Mecha-Chomps have grey canine bodies and move around on wheels. They appear to be based off of real-life toy, such as

In Mario & Luigi: Superstar Saga + Bowser's Minions, they are replaced by Mechakoopas.

Battle
The Mecha-Chomp wheels itself towards the Bros., then stops as the LED on its head cycles between red and green, eventually stopping on one of the two. The Mecha-Chomp then throws its head at the appropriate target: Mario if it is red, Luigi if it is green. Sometimes, if a Mecha-Chomp is damaged, it starts to malfunction, meaning that the colors it displays will be for the opposite targets (red for Luigi, green for Mario). Additionally, the item it drops while malfunctioning changes from a Nut to the School Emblem Badge; this makes the badge missable if Mario or Luigi's attack power gets high enough.
