Pumpkin Head

Pumpkin Head is the conjectural name of an enemy from Super Mario Galaxy. They are found near a haunted house level and resemble Splunkins, but they are actually Goombas wearing jack o' lanterns. They are found mainly in the Ghostly Galaxy.

They cannot be stomped like regular Goombas; to defeat them, Mario must Star Spin to break their Jack-o-Lantern helmets, then attack them. Ground Pounding them also works.

The species is probably a reference to Super Mario World. In that game, if you finish Star Road, the Goombas will then wear pumpkin masks as these do.

A similiar species called Splunkins are seen in New Super Mario Bros. and are usually found in Ghost Houses.
