Doppler commissions a ship called the RLS Legacy, on a mission to search for Treasure Planet. The ship is captained by the cat-like, free-spirited Captain Amelia (Emma Thompson), and the stone-skinned Mr. Arrow (Roscoe Lee Browne); the crew is secretly led by the half-robot cook Long John Silver (Brian Murray), who Jim suspects is the cyborg that Bones warned him about. Jim is sent to work in the galley, where Silver and his shapeshifting pet alien Morph supervise him. Although Jim does not trust Silver, they form a tenuous father-son relationship.
