Snifit (Super Mario 64)

Snifits, originally known as Snufits and known as Sniffits in Super Mario 64 DS, are ghost-like cousins of the enemies of the same name that first appear in Super Mario 64. They resemble their original versions, as they wear masks with bullet-shooting mouth nozzles, but are noticeably different in that they lack legs and float in the air instead of walking. The name "Snufit" is likely a pun on "snuff it," a colloquialism for dying, while "Sniffit" may simply be a typographical error.

Super Mario 64 / Super Mario 64 DS
In Super Mario 64, Snufits appear in the toxic maze of the Hazy Maze Cave and in the Cavern of the Metal Cap. They have a round Boo-like appearance and wear white masks. When Mario approaches a Snufit, it will shoot a burst of small bullets out of its mouth, although this action is preceded by briefly swelling up like a balloon before firing. Snufits can be defeated by jumping on them.

Sniffits reappear in Super Mario 64 DS, retaining their behavior. Here, their design is more faithful in appearance and shape to black-masked Snifits, but they have long sleeves and a long tail, making them resemble Boo Guys. Their heights from the ground have also been made less varied.

Mario Party 2
In Mario Party 2, on the board Space Land, the members of the Snifit Patrol are in fact this variant of Snifit, as proven by their speech icons. In Mario Party Superstars, they are replaced by ordinary Snifits.
