Jack O'Goomba

Jack O' Goombas, also known as Pumpkinhead Goombas, are pumpkin-headed Goombas found in Super Mario Galaxy and its sequel, Super Mario Galaxy 2.

''Super Mario Galaxy
Jack O' Goombas made their debut in Super Mario Galaxy. The only places they could be found in were haunted galaxies, such as Ghostly Galaxy. These pumpkin-wearing Goombas are capable of producing small blue flames in an attempt to burn Mario, yet the ability is lost when their pumpkin is destroyed. To break their Jack-o-Lantern Helmets, Mario must spin. Ground Pounding them, however, will destroy both the pumpkin helmet and the Goomba in one pound. Once they lose their Pumpkin cover, they are simply a regular Goomba. However, one should be careful to Ground Pound a Jack O' Goomba if it just produced a blue flame, as Mario would get burned if he touched it. Also, if one tries to jump on one, the pumpkin won't break.

''Super Mario Galaxy 2
The Jack O' Goombas later reappear in the sequel, Super Mario Galaxy 2. They have not changed much from the prequel, still wearing a pumpkin mask, releasing blue flames once in awhile. Yet these enemies are not limited to haunted galaxies, being found in such places as the Clockwork Ruins Galaxy.
