S2E24 A Trip to Morainia

King Randor tasks Adam, Cringer, and Orko with retrieving a potent energy crystal from his ally, King Moraius, in the frigid Ice Kingdom of Morainia. However, Skeletor has his own plans and follows them, seizing King Moraius and threatening to keep him captive unless the royal family hands over the crystal. Transforming into He-Man, Adam joins forces with Princess Janis, the King's daughter, and together they concoct a clever plan to rescue her father from Skeletor's clutches.
