Overview
The adventure follows Eli and his team of friends as they explore the caverns, challenge rivals and each other to duels, upgrade their cool gear, and generally have a blast in this never‐before imagined underground world. But there is a very real threat to Slugterra; Dr. Blakk is seeking to “ghoul” the slugs, transforming them into feral mindless weapons! No one has been able to stand up to Blakk’s powerful ghouls and army of henchmen…until now!
