Kids love to eat snow! It looks a lot like ice cream... hey, maybe it really IS ice cream! Johnny Boo and Squiggle are excited to find out, unless the Ice Cream Monster eats it all first. Armed with his gigantic and mighty Ice Cream Fork, he seems unstoppable...until all that cold snow in his tummy knocks him down for the count. Can Johnny Boo and Squiggle warm up their frozen frenemy with mittens from their secret mitten box? Or will they get lost in the silly blizzard forever? Don't worry, this snow day is guaranteed a very happy ending!
