Mad Jelly

This Mad Jelly (マッドゼリー, Maddo Zerii) has only appeared in Majora's Mask so far. It makes its appearance in the Great Bay Temple working in concert with a Gekko to guard the Boss Key. It does not attack on its own, but rather is directed by the Gekko. When Link enters the room, the Gekko yells and giant droplets of Mad Jelly fall from the ceiling. He then maneuvers around the Jelly, sometimes picking it up and throwing it at Link. When the first successful hit is dealt to the Gekko, he will jump to the ceiling with the jelly balling around him. when this happens, Link must avoid the jelly bubble when it falls or he will take a serious beating from the Gekko, who will eventually wind-up and punch him out of the bubble and return to the ceiling. In order to avoid this, Link must watch the jelly's shadow on the ground and roll out of the way. When this is achieved the bubble will bounce back up to the ceiling, where Link must quickly freeze it with an Ice Arrow. The jelly will fall and shatter, sending out the giant droplets once again, along with the Gekko, who Link must chase and then strike. This is repeated until the Gekko is defeated, at which time the Mad Jelly will melt and the way to the Boss Key will be accessible.

Chu Worms found in the Lakebed Temple as well as the Cave of Ordeals in Twilight Princess, may be related in some way to the Gekko and Mad Jelly.
