Sacchaman is a "fakemon" appearing in Pokémon Mid and Out. This is not an official Pokémon! It evolves from Rocake when leveled up while paired with Bouncweetz in a double battle and is the final evolved form of Yumull.
Sacchaman, unlike other Pokémon, seem to have a quintessential sense for cooking. Most chefs have found assistants in Sacchaman.
