Zip Toad is a Toad from Paper Mario: The Thousand-Year Door.
He is apparently very famous. When Mario gets on the Excess Express, he is supposedly in Room 1. Later, when Mario finds him with the waitress' Shell Earrings and Toodles' Gold Ring, he is revealed as Doopliss in disguise. After getting off the Excess Express, Mario gets an e-mail from the real Zip Toad, thanking him for revealing Doopliss' masquerade.
- In the letter that Zip Toad sends to Mario, Jr. Troopa can be seen in the background of the photo.
- Some of the movies that Zip Toad has been in are nods to movies in real life. For example, The Toad Warrior (which is named after the episode of the same name in The Super Mario Bros. Super Show!) is a parody of The Road Warrior.
