Muss T.

Muss T. is a Toad who is seen standing by the gaping hole where Peach's Castle used to be in Paper Mario. A letter can be delivered to him in the game, but other than that, he has no real purpose.

Muss T. was once fishing friends with Goompapa, Koover and Fishmael.

Tattle
"He's a Toad. He never fails to go for a walk, even if it's nasty out. He also loves cleaning for some reason. He cleans like crazy!"
