Ditto Leapfrog (Japanese: うけとめてメタモン) is the name of a Pokémon-based e-Reader application. It is a minigame starring Ditto. Three cards are required to play the Ditto Leapfrog application: Ditto, Granbull, and Snubbull.
In Ditto Leapfrog, the player takes on the role of a Ditto. In the game, a Kingler is tossing some Magikarp, Goldeen, and Seaking around. The objective of the game is to move around so that the water Pokémon will bounce off Ditto and back into the river. The game's pace moves faster as time goes on and the game is lost if Ditto fails to help three Pokémon get into the river.
