Mecha-Chomp

Mecha-Chomps are Chain Chomp-like enemies that appear in 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 a grey canine-like body, a retractable neck, a large LED display presumably used as an eye, and wheels for moving around. They appear to be based on 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.
