Phantump, Trevenant, Pumpkaboo, and Gourgeist are #SquadGhouls. Celebrate spooky season with these Ghost- and Grass-type Pokémon originally discovered in the Kalos region. From aiding Team Rocket’s Jessie in her villainous plots to joining Ash and his friends on heroic journeys, these four Pokémon scare up fun wherever they go. And since they also happen to be making their Pokémon GO debut during the Pokémon GO Halloween Mischief event—which will run from Friday, October 22, to Sunday, October 31—there’ll be plenty of opportunities to see this spectacular scare squad in action. Make a Toast to Ghosts with curated episodes of Pokémon the Series that feature Ghost-type Pokémon—including Phantump, Trevenant, Pumpkaboo, and Gourgeist.

Have a gourd time with this fantastically creepy collection of episodes. Remember that you can watch Pokémon TV here on watch.pokemon.com or using the Pokémon TV mobile app.
