We used rainbow sherbet cotton candy because of the fun colors. You could use peppermint-flavored cotton candy, which is holiday themed because of the flavor. If neither appeals to you, you could use mini marshmallows instead. Personally, I think marshmallows would pass better as snowman farts, which would also be an epic stocking stuffer for your fart fan. Maybe I'll have to design that one for my nephew for next year.
