Dream Ball

The Dream Ball (ドリームボール Dream Ball) is a Poké Ball introduced in Generation V that is only usable within the Dream World. The pattern of this ball is similar to Musharna. Like the Master Ball and Park Ball, it never fails to catch a Pokémon. It can only be used in the Entree Forest in the Entralink. Its distinctive pattern marks that the Pokémon within was caught in the Dream World, not the wild.
