Upright Cavern is one of the The 99 Caverns and it first appeared in Slugterra: Return of the Elementals.


Upright Cavern is a cavern that goes up right, (hence the name), but it's hard to get to, very few are able to climb up to it its why you fly up it, except for Dr. Blakk and his new found abilities.

The cavern is the home or at least it was the home of the Fire Elemental.
