Skidding Smoke

[Lat']

I know it sounds pretty dumb, but what is the object used as SRB2's skidding smoke (Also when Knux glides on ground)?

I looked around for it in the wiki but well... I never really had treasure hunter skills.

It's MT_PARTICLE.

Well, that seems obvious enough... I thought at first it was MT_DUST or something. Still, that might help me in future mods, if I ever want to change it's sprites.
