Pokémon Channel — the game focuses on watching television programs featuring Pikachu, a mouse-like Pokémon. The player living in the house can switch channels freely among the various channels of the television network created by Professor Oak, as well as explore one room of the house and several outdoor areas. Pikachu sometimes displays emotional reactions while watching, such as happiness or anger. The game takes place over several days, each of which includes unique story events. The GameCube's internal clock keeps track of time so that each in-game day lasts at least as long as one day in real time.
