Metal Mutt

"The Metal Mutt" is a recreational tool used to detect subterranean metal objects. It is first seen in "Arcade Mania," and Steven owned two of them but were later destroyed by the Drill Parasites.

Description
The Metal Mutt is a metal detector with dog-themed decoration including a collar with spikes around the base of the handle, purple ears, eyes, and nose, and a tongue affixed to its cylindrical head. It barks when it detects an metal object below the ground.

"Arcade Mania"
Steven uses the Metal Mutt to collect quarters to play games at Funland Arcade, and also collects another Metal Mutt with it.
