Spinner is an Arachnet Slug who belongs to Eli Shane. Spinner is listed as one of Trixie's favorite Slugs, although Eli has confirmed that Spinner is indeed the name of his Arachnet. He plays a main role in "The Journey Home" helping the rest of the Slugs get back to Eli by spitting web strands to reach higher areas. He is one of Eli's strongest Slugs.
