So in Gremlins is a kind of creature called a mogwai. Among the various rules is to not give him water, which would make him multiply and create the evil mogwai.
I only know about he the movie and its sequel, so I'm wondering if it was ever established somewhere else (Game? Book? Other?): Why didn't the snow make them multiply?
We know they multiply while in Gremlin form because of the pool, but the snow didn't seem to do anything to the caroling Gremlins. I would've expect body heat, if nothing else, to make the snow melt enough to act like the single drop of water that teacher used earlier in the movie...
Granted, come the second movie, they went rather crazy - a single camera flash reduced one Gremlin down to nothing but bones at one point. Plus all the references and 4th-wall breaking. So I won't complain if that movie is ignored for the sake of this question in regards to the first movie ;)
