Ghost Roaster, formerly known as Olav, is a skeletal ghoulSkylander in Skylanders: Spyro's Adventure. He is only available for purchase in the Darklight Crypt Adventure Pack. He is of the Undead element. Ghost Roaster is very curved and skeletal in appearance prior to falling into the Valley of the Undead. His head is skull-like with seeming razor sharp teeth, yellow eyes with orange pupils, and four pointy spikes atop of it. The bones that make up his arm and elbow are completely exposed with four fingers on each hand. He wears a black and almost worn out suit with a red neck collar that exposes the outline of his ribs. In place of legs is his tail which connects to his spiked ball and chain. Ghost Roaster is known for his relentless, undying appetite for ghosts (particularly evil ghosts). However, being a chef, he is good in the kitchen for making delicious recipes. Despite his scary behavior, he seems unfazed by pranks such as Camo's.
In Secret Agent Secrets, Ghost Roaster's flaw is revealed to be a desire to have his work recognized, even if by the side of the villains. Years being put aside in favor of newcomer Skylanders made him bitter towards them, until Stormblade expressed respect for what he did regardless of his threats. There was a time when Ghost Roaster was neither a ghost nor a roaster. Instead he was a chef living in a village high in the mountains. One day, while clipping wool from a sheep to use in a recipe, he accidentally fell into the Valley of the Undead and transformed into a ghost eating ghoul! After eating an entire spectral village, its Ethereal Ruler chained Ghost Roaster to a spiked ball as punishment -- its rattle heard as he wanders the night, warning nearby spirits. When Master Eon eventually heard of his predicament, he figured even a ghost eater could be useful. So he made Ghost Roaster a Skylander... after he promised to eat only evil ghosts.
