The Forest of Fear is one of the most perilous islands in all of Skylands, appearing only in Skylanders: The Machine of Doom. It is the location of the Chattering Key, an Arkeyan artifact that lies in the heart of this forest and is guarded by the stone wyvern, Fido. The Forest of Fear also houses colorful, but dangerous fungus called The Fungus Rings of Despair. Anyone who breathes in the powder that these fungi releases will have hallucinations of their worst fears coming to life.
