From WiKirby, your independent source of Kirby knowledge.
Mr. P. Umpkin is an obscure flying pumpkin-shaped enemy who first appeared in Kirby's Dream Land. It is similar in function to Two Face, showing two different expressions when it switches its side.
Appearance and behavior
Mr. P. Umpkin takes its name from its jack o' lantern like appearance. It remains dormant on the wall until Kirby passes by, then springs to life with a different face. From then on, it chases Kirby, spiraling around him until it is defeated or hits him. It moves generally faster than its Normal game counterpart.
Kirby's Dream Land
Mr. P. Umpkin first appears in Kirby's Dream Land. It appears in place of Two Face in Castle Lololo when Extra Game is being played. As such, Mr. P. Umpkin functions much the same as Two Face, though it deals twice as much damage to Kirby when it collides with him. Mr. P. Umpkin is worth 600 points when defeated.
Kirby's Dream Course
Mr. P. Umpkin returns in Kirby's Dream Course. Here, it only uses one face, and looks more similar to a classic jack o' lantern. It hovers in place a medium distance above the ground in various courses, and can be defeated by colliding with it.
Appearance in Kirby: Right Back at Ya!
Mr. P. Umpkins retain their design in the pilot episode for Kirby: Right Back at Ya!, and appear in that episode alongside the Sweet Stuff, the Haboki, etc.
