Box of Tricks

In a Red Magic lesson, Muru teaches Tom and Twigs the Gripping Bear spell. As a test, he asks them to deliver a mysterious box to Treetog, but in order to deliver the box, they must really concentrate! As they carry it, they start getting distracted by a strange voice and an amazing spell coming from the box. Puffy and Stink arrive, and things go from bad to worse when Twigs, the Mushas and Tom end up inside the box. Will they ever get out? And what's Muru going to say?
