The Wizard of Ice - S4.E22

A boy loses his ball in the water and he falls in trying to get it. The Snorks save him, and they have to save a forest from a fire. The fire was started by a little fireball named Ember. She was evicted from her home by an Ice Wizard who has frozen her home and the Snorks try to help her get back. Junior wants nothing to do with his whole adventure until he hears about a golden river (with real gold) on the island. On the island, they find out that the Wizard put a spell on the people to turn them cold. It's up to the Snorks to help out Ember, but the Ice Wizard freezes them. Junior finds them and the Ice Wizard likes his selfish ways and recruits him as his assistant. Ember tries to get through to Junior by having the Wizard snub her out, and when he sees the light, Ember comes back and destroys the Wizard.
