Melt 3/4 cup of red candy coating in the microwave. Dip the peanut butter cups into the candy coating and set them on parchment paper. Sprinkle with red crystal sugar and allow the candy coating to harden.
Unwrap the Hostess Sno Balls and flip them over so that the flat surface is right-side-up. Melt 3/4 cup of white candy coating in the microwave. Cover the bottom 1/3 of the Sno Ball with the melted candy coating. Cover the white candy coating (or frosting) with white crystal sprinkles.
Next, melt 3/4 cup of the blue candy coating in the microwave and cover the remaining 2/3 with it. You can use blue frosting, instead of blue candy coating, for easier spreading for younger children.
Before the candy coating sets, add a few snowflake sprinkles. You can use a tweezers to place the snowflakes in the exact place.
While waiting for the candy coating to set, make fruit leather scarves for the snowmen. Cut the fruit leather into narrow strips and wrap it around the snowman. Since the fruit leather is sticky, it will stay in place.
Remelt the remaining white candy coating in the microwave and spread a little on the back of a snowman and set it into the center of the snow globe.
Remelt the remaining red candy coating in the microwave, put a dollop in the center of the red base and attach the Hostess Sno Ball. Hold it there for a minute or two while it hardens.
