Slugterra - Season 2

The Dark Slinger and his marauders have invaded Slugterra! But there's more to this new threat than meets the eye. Eli must fight a very different kind of duel to save Slugterra...and himself.

A new member joins the Shane Gang! His name is Junjie, and he is a master of the mysterious slugslinging art of Slug Fu. But even with the power of five slingers, the Shane Gang find themselves in over their heads trying to protect the ancient Elemental Slugs.

The Shane Gang and Junjie race across the 99 caverns, fighting to keep the powerful Elemental Slugs out of the hands of the Goon and its new ally.

The battle to save Slugterra and the Elemental Slugs reaches its climax as the Shane Gang face a final showdown against their foes.

To master the mysterious slug-slinging art of Slug Fu, Eli must train alone with Junjie. That means leaving behind the rest of the Shane Gang-as well as all of Eli's slugs, and the ultra-powerful Elementals! Pronto vows to keep the Elementals safe, but proves so annoying that they run-er, hop-away!
