The Poké Doll is an item that first appeared in Generation I as a battle item. It has the appearance of a small Clefairy doll which is capable of allowing the player to instnatly escape from a wild Pokémon battle. Poké Dolls can be bought in the Celadon Department Store in the Kanto region and found in the Battle Pyramid. Since Poké Dolls are readily available, the Trainer can trade one of their Dolls to receive TM31 from the Copycat in Vermilion City.
In Generation III, the Poké Doll was replaced by an item of similar usage, the Fluffy Tail. Similarly, Generation V introduced a newer variant of the Poké Doll, this time it was named the Poké Toy.
Through exploiting a glitch present in Generation I, a Poké Doll was capable of defeating the Ghost Marowak at Pokémon Tower, although this glitch was later rectified in the remakes.
