In the 1960's Rankin/Bass animated Christmas Special Frosty the Snowman, would Frosty have come to life if he had not been made of the special "Christmas Snow?"
I know it's supposed to be the magic in the hat that brings him to life, and he even goes back to a normal snowman when the hat is taken off of his head... but, the characters (The Narrator, Santa Claus) emphasize how special and magical Christmas snow is, and what it can really do.
Would the hat have done the same thing to a regular snowman that had been made out of run-of-the-mill snow?
