Dribble and Spitz's taxi is a taxi driven by Dribble and Spitz. It was created by Dr. Crygor. It resembles a run-of-the-mill taxi, but it is able to turn into a spaceship and rocket through space. The taxi has appeared in every one of Dribble and Spitz's stories.
WarioWare, Inc.: Mega Microgame$!
In WarioWare, Inc.: Mega Microgame$!, Dribble and Spitz first tune up the taxi at Diamond Taxi before picking up a customer, and the stage subsequently takes place in the taxi, with the music coming from the car's radio, the lives being represented by little Spitz dolls hanging from the car's roof, and the current level being displayed in the odometer. The colors in the taxi also change to the reflect the stage's difficulty. Of note is that the customer's fare is automatically set to $77,777 when Dribble turns it on.
In WarioWare: Twisted!, the taxi is being driven by Dribble and Spitz again along Interstate 310 when Spitz starts playing around with its radio (this again sets the music for the stage). It then suddenly breaks down on the road, and Dribble and Spitz get to work repairing it. Whenever a microgame begins, the taxi's hood pops open and it zooms inside. During the stage, the taxi smiles when a microgame is won and gets angry when a microgame is lost. After completing all of the microgames, Dribble and Spitz transform the taxi into a spaceship and fly into space, where they pick up Ocktor.
WarioWare: Smooth Moves
In WarioWare: Smooth Moves, Dribble and Spitz are cleaning their taxi when Alien Mitzi asks them to take her to Tomorrow Hill, and Dribble promptly ferries her there. As in WarioWare, Inc.: Mega Microgame$!, the interior of the taxi is where the stage takes place, and the details from that game are repeated in this one (excluding the change in color; the stage does not increase in difficulty).
WarioWare: D.I.Y. Showcase
The taxi is also featured in Dribble and Spitz's story in WarioWare: D.I.Y. Showcase.
