Jessie's Pumpkaboo is a ghost/grass-type Pokemon and the first Pokémon Jessie from Team Rocket obtained in the Kalos region.
Pumpkaboo appeared in The Bamboozling Forest! while Team Rocket was lost where it appeared out of the ground after Jessie tripped over its horns. Jessie immediately threw a Poké Ball at it and caught it easily in one go.
Pumpkaboo was used to help Jessie compete in a Pokémon Showcase located in Courmarine City. But lost was it got the least amount of votes from the audience.
Pumpkaboo was later used to compete in the Pokémon Sky Relay tournament. But despite managing to win the first lap, it was disqualified, along with its team when Meowth's Pelipper machine was exposed.
Not much is known about Pumpkaboo, but it has a habit of flashing the lights in its stomach. It also shows that it has no problem listening to Jessie's commands.
