ORIGIN:
An interplanetary transport ship has been in service for centuries, yet no one on board, be it passenger or crew, throughout the ship's entire history and despite many different owners, has ever been so desperate for food that they ever bothered to search the very back of the freezer, where an unidentifiable lump of old (presumably) food has been sitting. When the ship is finally decommissioned and sent to a Black Hole Compactor, the gross item quickly evolves into its final form.
ABILITIES:
Decay Gas: breathes mist that causes items to slowly decay
Knock Attack: floats into enemies to knock them over
Mega-Freeze Gas: breathes mist that turns stars into frozen dead ones
