From Bulbapedia, the community-driven Pokémon encyclopedia.
Make A Dash is the name of a Pokémon-based e-Reader application. It is a short cartoon starring Rapidash. Only one card is required for the Make A Dash application: Rapidash.
In Make A Dash, a Rapidash is shown running briskly across a field. When it reaches a post, the game will show how fast Rapidash's "MAX Speed" was. The MAX Speed of Rapidash changes every time the application is scanned into the e-Reader.
