Original Airdate: ?/?/1983
In a forest Orko, Teela, Man-At-Arms, Adam and Cringer are having a picnic. A volcano erupts, sending earth tremors rippling throughout the land and producing a large chasm stranding two children on one side. A rock creature, Rabar, emerges from a now-unsealed cavern entrance and appears to be threatening. He-Man uses his sword and some Iron Vine to pull the chasm together. Rabar takes the Sword of Power and the cavern closes behind him.
The group head back to the Royal Palace, where Teela is angry over Adam's sudden disappearance, and wants He-Man to speak to Adam. They all head off back to the cavern and find cave corridors inside, along with a huge cavern, which houses a pit to the center of the planet. Rabar swings the Sword of Power high above his fellow rock people and declares himself their leader.
Togar steals Man-At-Arms' laser gun and begins firing, one shot careening into the city's support beam. He-Man holds up the main beam and with the help of Rabar and Togar save their community. Rabar and Togar toss the sword and the laser gun into the pit. Later, Orko appears with the sword, saving the day. Adam convinces Teela that He-Man has lectured him as she wished.
