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.
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.
