Eli has added some awesome new slugs to his arsenal: the ELEMENTALS. But the Elemental Slugs are ancient, extremely powerful, and temperamental, and Eli can't control them. Junjie, the newest member of the Shane Gang, has the solution: Eli must learn SLUG FU, the ancient form of slugslinging that Junjie mastered when he lived in the Eastern Caverns. Slug Fu is the art of guiding and controlling a slug in battle—a skill that only the greatest slugslingers can master. (thetvdb.com)
