First up: I found both of these on Major Spoilers, which is where I actually find quite a few of the embedded videos I post. (Very useful for low content days like this one.)
Second: This is awesome. I want a snow globe based on this.
Apparently, those are actual sculptures (though presumably not snow sculptures); the only "fake" part is the snow.
Third: I don't know anything about this band or the song, but I think that singing snowman is incredible.
Especially the blinking.
Delivering holiday content days late for years. Go me.
