Mecha Grunty is a robotic Grunty created by Dr. Kepel in Mac Anu. It appears in dungeons and fields, crashed and depleted of power. If the player powers it up with chim-spheres, it will recover and fly off, only to crash again in a different area, leaving an item behind. Saving it 50 times will allow Mecha Grunty to finally have a successful take-off, and the player will be able to obtain rare equipment from Dr. Kepel. This is only required to be done 30 times in Redemption, with a follow up quest able to take place immediately after.
