SlugTerra: Return of the Elementals

A fresh ally joins Eli and the Shane Gang. Junjie, formerly the guardian of the Eastern Caverns, is a master of the slugslinging art of Slug Fu. But even with the power of five slingers, the Shane Gang find themselves in over their heads as they race across The 99 Caverns in pursuit of the Legendary Elemental Slugs. The five Elementals are ancient slugs of great power, and the forbearers of all slugs found in SlugTerra today. In the wrong hands, they could bring Slugterra to the brink of destruction. So when an evil alliance starts hunting down the Elementals, Eli and his friends, old and new, set off in pursuit of the greatest threat their world has ever faced!
