Some Pumpkinmon reside in the Holy Capital. They bounded Marcus Damon, Agumon, Thomas H. Norstein, Gaomon, Yoshino "Yoshi" Fujieda, and Lalamon. One Pumpkinmon serves as Baronmon's right hand Digimon. When it came to Akihiro Kurata's next attack, some Pumpkinmon were seen at Baromon's assembly. When ElDoradimon was brought to the Digital World, two Pumpkinmon used their attacks on the Gizumon-XT causing them to destroy each other.
