A Rare Candy is an item that can level up a Pokémon by one level per candy. Rare Candies can be obtained as a tier 1 special drop. It is a possible drop from boss Pokémon. Using a Rare Candy on a Pokémon owned by the player will give it the Rare Candy and level it up. While holding a Rare Candy, Pokémon will follow the player around.
