The movie star Zip Toad.
“You're cool, baby... but I'm cooler!”
—Zip Toad, Paper Mario: The Thousand-Year Door
Zip Toad is a famous movie star with an ego who is one of the suspects in the investigation on board the Excess Express in Paper Mario: The Thousand-Year Door. Zip Toad's name is a pun for ZIP code. He's in room 001 on the Excess Express. However, it turned out Zip Toad was actually Doopliss in disguise (on the Excess Express), apparently hired by Beldam of the Shadow Sirens. Later, the real Zip Toad sends Mario an e-mail, containing a picture of the actor in front of a window. In the e-mail, Zip Toad told Mario that he was going to film a movie in Toad Town called On Golden Toad 2. He also reveals more about his movie career by quickly mentioning another film that featured him: The Toad Warrior.
- I KNEW I knew him! That's Zip Toad, the movie star! Women go NUTS for him! Y'know, he's hot and all, but he seems pretty stuck up about being famous. I guess all celebrities are kinda like that. It's too bad, 'cause I kinda liked him...
