1x11 - Dungeons & Dragons

A sudden earthquake splits the ground the kids walk on and Hank falls in. When the kids come to his aid, they find a box. The Dungeon Master informs them that it is Zandora's Box, a magical device that contains good or bad things, depending on where it is opened. He also informs them that the box is the key to them getting home. They must first free Zandora, who can be released from her current place of captivity by placing the box in the shadow of the skull on Skull Mountain at exactly noon. Once free, Zandora can tell the kids where to place the box to allow them to return home. But when Venger becomes wise to their plans, he isn't going to let them succeed in any of their plans.
