Frypolar

Frypolar is a mini-boss from The Legend of Zelda: Oracle of Seasons. He appears as a cloud of elemental energy with a face and arms, changing from fire to ice. In fire form he spat two trails of fire after Link, in ice form, he sent an ice crystal along the floor attempting to spear Link from underneath with it.

Frypolar could be switched between his icy and fire forms with a shot from the mystery seeds, although this did no damage to him. In ice form, Frypolar could be damaged by a shot from the ember seeds. In fire form, he was immune to all of Link's seeds. Link had to shoot the ice crystals that he made with mystery seeds. This changed them into a smaller crystal that he could then throw at Frypolar to damage him.
