Rocky is a Hop RockSlug who belongs to Eli Shane. Eli won him during the SlugSlingingcompetition of the first two episodes. Like Joules, Rocky showed a specific interest in being the Slug to join Eli's arsenal, while the other members of his former arsenal weren't so keen on the sort of adventure life with a Shane promised. Eli doesn't use Rocky very often. Rocky's first real use came in "The Slug Run" -- hence his presence, rather than Joules, throughout the episode in Eli's bandoleer -- when he was used to knock down several plants which Chiller then frozen into an ice wall, slowing down the Shadow Clan members in pursuit of Eli.
