When in the Forest of Magi Oar, the ThunderCats send WilyKit, WilyKat and Snarf to search for firewood. After they return, they start a fire and lay down to rest. Lion-O then throws a special piece of firewood that releases several seemingly evil spirits around them. After Lion-O and the rest of the ThunderCats cannot defeat them, the ThunderCats meet the Wood Forgers who have a talent for using paper magic in combat.
