Eli Shane is determined to be the greatest slugslinging hero of them all. To do it, he'll need to collect and train an army of little critters called slugs. When these magical creatures are fired at 100 MPH out of a high-powered blaster, they transform into powerful battle beasts! The adventure follows Eli and his team of friends as they explore the underground caverns of Slugterra, challenge rivals and each other to duels, upgrade their cool gear, and generally have a blast in this never-before-imagined 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!
