The trio manage to calm the goddess down and she introduces herself as Xandra, the Goddess of Adventure. She initially mistakes Donald, José, and Panchito for The Three Caballeros but is disappointed to find that they are their lackluster descendants. When the trio tell her that they're looking for treasure, Xandra teleports them to Crete where they fight a Minotaur within the hidden labyrinth. Despite their differences, they manage to prove themselves to Xandra as the Caballeros's rightful heirs by finding three magical amulets left by their ancestors. Meanwhile, Baron Von Sheldgoose discovers a magical staff containing his evil ancestor Lord Felldrake.

Xandra saves Donald from the monkey-bat creature, which turns out to be Felldrake's old minion Leopold the Horrible. He flies his master and Sheldgoose to Egypt, and an ancient pyramid. The Caballeros follow, learning that the pyramid is really a space ship, and accidentally launching it to the moon. On the moon, Felldrake awakens an army of Moonbots he plans to use to conquer the Earth. By working together, the Caballeros manage to use their own robot to knock the villains into space while Xandra defeats the Moonbots. Written by whatsitsgalore

The Caballeros arrive, and Xandra can't wait to introduce them to the ancient Roman gods. But it seems her heroes have gone to seed and given up combating evil. While Donald, José, and Panchito battle giant termites, Xandra gives the gods a much-needed pep talk, encouraging them to join the fray. Felldrake's power seems limitless as long as he holds the cosmic fruit, but the Caballeros distract him long enough for Xandra to shoot the fruit out of his hand, blasting the villains to their next destination.

The resulting party keeps the stone giants distracted and enables the Lava Lizards to build a stone bridge to the mainland so their queen can destroy the world. Xandra brings the Caballeros to the island, where they trick one of the Moai into destroying the bridge.
