Exile Isle (S03E10)

The Thundercats capture the Lunataks and, fed up with their wicked antics, decide to banish them to Exile Isle, a remote island in space far from Third Earth. Upon their arrival, the Lunataks encounter Captain Cracker, a pirate previously exiled by the Thundercats. Teaming up, they send out a distress signal to a nearby ship. When the vessel approaches, the Lunataks unleash a thick fog, causing it to crash. They then repurpose the ship's engines to shift the island's orbit towards Third Earth. Meanwhile, Snarfer, returning from Thundera, collides with the island. Lion-O sets out to save Snarfer and prevent the island from detonating due to a dangerous gas. He ventures without the Sword of Omens but is unexpectedly aided when the Sword flies to him. Using dirt to halt the engines, Lion-O ultimately manages to redirect the island back to safety.
