Snifit (Super Mario 64)

Snufits, also known as Sniffits , are ghost-like cousins of Snifits. They have a round boo-like appearance, and have a white mask.

Super Mario 64
They appear in Hazy Maze Cave, specifically Behind the Waterfall, in Super Mario 64 and Super Mario 64 DS. When Mario comes close to one, it will shoot a burst of small bullets out of its mouth like a Snifit, although this action is preceded by briefly swelling up like a balloon before firing in Super Mario 64. Snufits can be defeated by jumping on them.

Super Mario 64 DS
They reappear in this game, behaving very similarly to previously. Unlike the original version, their design was more faithful to the black-masked Snifits, save for the lack of legs and ability to float, which is the same in both versions of the game. Their shape was also more like the regular Snifit design, thus resembling a Boo Guy.

Mario Party 2
In Mario Party 2 on the Space Land board, the members of the Snifit Patrol are in fact Snufits, as proven by their speech icons.
