Slugterra: Ghoul From Beyond

Just when the evil Dr. Blakk has been defeated and it seems like Eli Shane's duties as protector of Slugterra are getting easier, a new danger emerges from beyond the 99 caverns. Eli and the Shane Gang rush to the rescue, but nothing can prepare them forwhat they encounter: a slug that can do something no one in Slugterra has ever seen - or heard - a slug do before! Traditional slugslinging no longer applies. Eli will have to engage in a very different kind of duel to save Slugterra... and himself!
