Slugterra: Eastern Caverns

The time has come for Eli and the Shane Gang to accompany their new friend Junjie home to the strange and beautiful Eastern Caverns. But when they arrive, they are shocked to find a world darker and more dangerous than Junjie remembers. The sinister Emperor's henchmen have pillaged every cavern of its slugs, and without the slugs' energy, the Eastern Caverns have fallen into ruins.
