Ditto Leapfrog is a Pokemon e-Reader game for the Game Boy Advance. In order to play Ditto Leapfrog three different Pokémon e-Reader cards must be scanned. The cards required are: Ditto (#51), Granbull (#61), and Snubbull (#101).

In Ditto Leapfrog a Kingler Pokémon will throw fish type Pokémon from the background to the foreground. The player must move Ditto (Who is in the foreground) left or right in order to make the fish Pokemon bounce off and into the water. Once three of the fish Pokemon have been missed the game will be over.
