Slugterra

This is Slugterra, a place beneath the surface where people have to sling slugs to survive, people in slugterra don't know about the surface world and vice versa. (for those of who haven't watched the show. down in slugterra people are given blaster that fire slugs that when shot they go to 100 mph and then they transform and have special abilities different abilities for different types of slugs) you are the son of Eli Shane and Eli has fallen and he sent Burpy (who is an infernus slug) to get you and show you the letter in Eli's final moments and the letter tells you all you need to know and now you just finished the drop to slugterra to become the new shane and the rest is up to you.
