Flame Feeder is a fiery monster bought by Dedede to entertain tourists in the episode Tourist Trap. In its original form, it resembles a small orb with a small flame inside it. However, when Dedede tosses it into the volcano during the tour, it quickly absorbs the lava and turns into a large jellyfish-like creature. Flame Feeder goes on a rampage, hurling globs of lava at the tourists. Kirby comes to the defense of two fallen tourists and becomes Fire Kirby by inhaling its flames. Tiff also calls the Warp Star. Kirby flies around Flame Feeder and gets a clear shot at him. Kirby's fire only strengthens it however, and it knocks Kirby off the Warp Star. Thinking ahead, Tiff convinces the tourists to throw some ice cubes to Kirby from one of the thermos she made them bring with them. Kirby gets the Ice ability and freezes Flame Feeder, which in turn destroys it.
Flame Feeder first appeared as a small glass orb with a small flame burning inside. Once it's thrown into the volcano, the lava inside begins to glow magenta. In its strongest form, Flame Feeder's body resembles that of an ocean jelly. Its body is made of lava and it has two whitish eyes in the center of its head. Its two large tentacles emit a large flame on the ends of them. After being blasted by Kirby's ice, it shrinks and turns a bright neon blue.
