“I'm looking for this guy who defrauded me with a fake credit card the other day. If you find that jerk, give him a whupping for me!”
Goomther is a Goomba that wears a green hat around in Paper Mario: The Thousand-Year Door. His name is a portmanteau of "Goomba" and the German name "Günther". Goombella uses him as a demonstration for her Tattle ability. (Oddly, his demonstration Tattle is different than that featured in the rest of the game.) He seems to get ripped off a lot, as whenever talked to, he bemoans having, for instance, his credit card stolen by Larson. All he does all day is walk around Rogueport, where he lives. He is a very minor character in the game, the only need to see him is when he has a trouble or is involved in one.
