Synopsis: In Ghoul from Beyond, a new danger emerges from beyond the 99 caverns, and Eli and the Shane Gang rush to the rescue. But nothing can prepare them for what 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.
