Forcefully given to a Poké Mart clerk on a dark, moonless night, the Prison Bottle contains the true power of Hoopa! Use the bottle, and for a mere three days will Hoopa be unbound, becoming the Djinn Pokémon. This removes its ghost-like qualities, making it a Psychic/Dark dual-type instead. In this state, Hoopa’s power is increased, with legend telling of it stealing a castle with its loop for the treasure inside.
