Hold Down Hoppip (Japanese: ハネッコをとばすな Don't Let Hanecco Float Away) is the name of a Pokémon-based e-Reader application from the Expedition Base Set. It is a minigame featuring Pichu. Only two cards are required to play the Hold Down Hoppip application: Pichu and Hoppip.
In Hold Down Hoppip, the player takes on the role of a Pichu. As the title implies, the objective of the game is to keep five Hoppip from floating away. The Hoppip are tied down with ropes but are floating away anyways, so the player has to run around and pull on the ropes to keep the Hoppip from disappearing. The Hoppip float away faster as time progresses, and the game is over when a Hoppip floats off the screen. The e-Reader will record a player's high scores for later reference.
