Wubbzy gets a strange little animal called a Fleegle from the Pet Truck Man. He thinks he knows how to take care of a pet, so he throws away the care manual. Wubbzy feeds it candy instead of the right food, and it starts growing. And growing, and growing... Soon it’s a huge animal rampaging through Wuzzleburg, eating every sweet in sight! It’s all Wubbzy’s fault, so he has to figure out how to stop it!
