Dribble & Spitz
Dribble, a big bulldog, and Spitz, a little cat, work for Diamond Taxi. One rainy day, they pick up Bill or Bob or Fifi or whatever name you chose to call yourself under the bright lights of downtown Diamond City. As they drive, they change the radio station to an ingratiating, poppy tune. At this point, the player starts Dribble and Spitz' sci-fi games, a wacky collection that seems drawn from action movies of all types, as players will shoot UFOs, dodge ninja darts and fight an Ultraman-style Bowser-versus-Mario fight.
When the player beats Dribble and Spitz's games, he or she gets to see them delivering their character to their destination: the beach. With a flash, the passenger transforms into a mermaid - or merman - and leaps into the ocean. Dribble and Spitz forget to collect their fare.
The mechanics show up again in WarioWare: Twisted!, again in their taxi cab. They're driving down Route 310, which apparently cuts right through Diamond City when Spitz turns on the radio as a means of staying awake. The action takes a drastic toll on the cab, however, which promptly blows a gasket. In the meantime, the player takes over and plays Dribble and Spitz's set, "Steer Clear," which has the player both tilting the Game Boy and pressing the A button. In the end, Dribble fixes the cab, which blasts into space. Up in the stars, an alien hops in. "Where to?" they ask, to which the alien promptly responds with "Take me to Club Sugar!"
Dribble and Spitz do not have their own game set in WarioWare: Touched!, however they do make cameo appearances in other characters story scenes. Also, it's their taxi cab - still in hover mode - that delivers new characters to the screen where players select whose games they'd like to take on.
