From Bulbapedia, the community-driven Pokémon encyclopedia.
Dream Eater is the name of a Pokémon-based e-Reader application. It is a minigame featuring Drowzee. Seven cards are required for the Dream Eater application: Espeon, Hypno, Jynx, Smoochum, Drowzee, Drowzee and Mr. Mime.
In Dream Eater, the player assumes the role of a Drowzee. The objective of the game is to put a Primeape to sleep using Hypnosis without being seen by it. The player must move left and right to keep out of Primeape's line of vision. Every time Primeape is successfully put to sleep, the player goes up a level and the difficulty increases. The game is over when the player is seen by Primeape.
- This game requires more cards than any other Pokémon e-Reader application (not counting the Construction: Action/Melody Box applications), needing a total of seven cards.
