#20 "The Ghost of Maiden's Peak"

    The gang, and Team Rocket, arrive at Maiden's Peak, where a festival is being held. Brock and James both briefly spot a beautiful girl, who they immediately fall in love with. An old lady warns them that a beautiful girl will bring them to ruin, but they can't listen, they're already wayyy smitten. Later, they hear a tale of the rock that stands on Maiden's Peak - it is in the shape of a maiden, which is how the plateau got its name. This lady stood, waiting for her lover to return to her, and waited so long that she turned to stone.

    A painting of the girl when she was alive is shown, and it's exactly the same as the girl James and Brock saw! But she has been dead for thousands of years... the two hormone-driven guys don't care, and go as if in a trance to the rock. Later, Jessie/Meowth and Ash/Misty are looking for their friends, and run into each other. Finally, they find Brock and James, babbling incoherently about loving the maiden. Pikachu shocks some sense into them.

    The old lady they met before says she can sell them anti-ghost stickers, which will prevent the maiden from being able to take them. The maiden, every year, comes and targets guys, apparently. The gangs plaster the stickers all over the lady's shrine, and all over James/Brock. But a strong wind blows all the stickers away instantly, and the maiden appears. She says she has been waiting so long that she will take James and Brock. Jessie runs in to save James, and Ash's Pokédex suddenly picks up that the maiden is actually a Gastly - a ghost Pokémon good at hypnosis and creating illusions.

    They fight Gastly without success, because it changes forms easily to suit its opponent. But then, the morning comes, and Gastly cannot stay in sunlight. It leaves for another year. This Gastly is actually helping the REAL maiden's ghost, in keeping her legacy alive (and making a few bucks on the side by disguising itself as the anti-ghost-sticker-selling lady). Ash-tachi and Team Rocket enjoy themselves freely at the festival.
