A chilly wind is blowing, and, in an unexpected moment, the ghost of the woman then appears in front of Brock, saying she was waiting for him! Brock then gets happy to see her again, and chooses to follow her. Meanwhile, Team Rocket are sleeping in their sleeping bags. The portable clock rings, and Meowth tells Jessie and James that it’s time to steal the painting, as it is midnight. However, the ghost of the maiden send a hypnotic wind, putting back Meowth and Jessie to sleep, but approaches James, and tells him that she waited so long for him, too.
When the sun rises, Brock is nowhere to be found. Ash then crosses paths with Jessie, who starts doing their dumb motto alone, since James is gone, too! Suddently, Brock and James appear, floating and babbling like morons. Pikachu thundershocks the two men, but in vain. They then think they maybe did ‘who knows what’ with the ghost of the Maiden, but the old hag tells the gang that they got possessed by the ghost of the girl. Each year, the spirit of the girl tries to seduce men, possess them and leave them possessed and acting like idiots. She then suggests the gang to buy anti-evil spirits stickers, and sticks them wherever they don’t want evil spirits to be.
So, when night falls for the second time. Ash and Misty sticks the stickers all over the shrine as well as on Brock and James! Then, the old lady warns them ; the soul of the maiden is back! The stickers get blown away by the strong winds, and James cries, wondering why the stickers are not working, and Jessie tells him they got them…for free. As the maiden beckons Brock and James to her, Jessie shoots at her with a bazooka, but it has no effect on her. The spirit then gets angry and summons ghastly skulls, scaring the whole gang. Ash uses his PokeDex and tries pointing it towards the skulls, but in vain, as the PokeDex does not recognizes the skulls as being Pokemon, but when Ash points it at the maiden, the PokeDex alerts that she is actually a Gastly!
Being caught red-handed, Gastly turns back to his original form, while Ash sends out his Charmander. However, the Gastly isn’t dumb, for it creates an illusion of a fire extinguisher shooting water at the fleeing Charmander, believing it is real water! Meowth tries to attack, but Gastly then creates a ball of catnip (an illusion, of course) with Meowth playing with it. Jessie sends out her Ekans, but Gastly summons a mongoose, the sworn rival of poisonous snakes. James sends out Koffing and orders it to use Poison Gas, but the same mongoose stomps it, wearing a gas mask. As a last resort, Ash sends both Bulbasaur and Squirtle at the same time. Gastly then creates a Venusaur and a Blastoise, but decides to make the two as one by fusing them, creating a half-Venusaur, half-Blastoise creature (dubbed ‘Venustoise’ by fans) but it disappears when Misty pulls out a cross, garlic, holy water and a spear. Gastly then screams as the bell is tolling. It explains it is not a vampire, but, being a ghost, it hates light, and disappears when the sun’s rays comes.
During the festival, everyone is dancing and having fun with a special acivity where tiny boats with candles are sent on the sea to guide lost spirits home. Then, the REAL soul of the maiden comes and thanks Gastly for keeping her legend alive. Gastly promishes her to find her lover, since it is a Ghost Pokemon, and will tells him his wife is waiting for him.
