This article contains information that relates to the non-canon game Pikspore, which was created by Neini.
The Gaspook is bulborb's ghost and a relative of the Blaspook and the Ghost Bulborb. It is a floating bulborb skull with a cloud of red mist trailing from behind it. It attacks either by floating over to Pikmin and eating them or by spewing poison gas from its mouth at them. Attacking it from behind will not work due to the poisonous gas it produces so it must be attacked from the front. Its skull can be carried for seeds or Pokos are it is defeated. Gaspooks produce the distorted sounds of a Red Bulborb's death screams.
- "This creature appears to be a close relative of the ghost bulborb. Like the aforementioned creature, it seems to be inexplicably deceased and yet alive. This paradox is no simple hallucination, as the poisoning of my Pikmin has proved."
- "Inedible due to its lack of edible matter."
