Original Airdate: ?/?/1984
When Mer-Man's mechanical sea monsters attack an old man's fishing boat, He-Man is able to save the man but not his boat. Jacob, a hermit, says that fishing was his entire life and that he has no need for people, but the Widgets decide to take Jacob into their home. Trap Jaw suggests Mer-Man build new robots using Coridite, the crystals the Widgets mine.
Mer-Man attacks the Widget fortress and begins to flood their mines when Teela pays a visit. Mer-Man quickly escapes into his own waters, but He-Man follows behind and takes the Coridite from him. He-Man uses Man-At-Arms' new Wind Raider, with Coridite-enhanced rocket boosters, to fly into outerspace. He pushes the moon, forcing the tide to go down and the floodwaters to flow out of the Widget fortress. He pushes the moon back in place and returns to the fort, where Jacob agrees to be the Widgets' mayor.
