There's the milk one. That's the only other one I can think of. I'm not sure why you'd want to try some of them though, seems like they just make you sick. My mom always told us when we were little that if we played chubby bunny we would choke on the marshmallows and die :P

the only other challenge i can think of is the oreo one :p

Spicy foods challenge. Specifically, hot peppers. See who can eat one and go the longest without begging for something to cool their mouth off XD
