The land First Earth knew as Egypt and the Thundercats now know as home has some visitors — a ship full of pirates called the Berserkers, Berserkers, BERSERKERS! (No, not those Berserkers, although their leader Hammerhand is certainly deranged enough.) They've come to hunt — specifically, unicorns. Snarf gets himself captured helping one escape from them. Lion-O's saving another unicorn from being eaten by a hostile tree when he gets the alert. He goes looking for the beach he saw in the sword and ends up finding the whole herd of unicorns and their two elf-like keepers. Although they're suspicious of him at first, the keepers come to trust him, especially after he saves the unicorns from the Berserkers. Unfortunately, they still get away with Snarf and the baby unicorn. Lion-O manages to catch them with some help from the Ring of Power his unicorn friend gave him, and a sea battle ensues with quite the unexpected ending for the time...
This episode provides examples of:

- Gender-Inverted Trope: In-Universe! The keepers are stunned when they learn one of the unicorns trusted a man enough to give him her ring — "No man has ever worn that ring!" (Maybe they wouldn't be so surprised if they knew he was much younger than he looks...)
