That's Magic

Marlon the Wizard visits Rainbow’s End to collect some ingredients for one of his spells. He asks Yam Yam to look after his magic wand and spell book whilst he goes away with Onny to collect the gear. Yam Yam plays around with the wand and ends up turning several of the Boblins into animals including turning himself into a frog. The whole thing is resolved when the Wizard arrives back and reverses the spells.
