Frosty the Snowman is a snowman that appeared in "Phineas and Ferb Christmas Vacation!" after Ferb wonders were Perry is, Perry appears walking through the snow, then, he puts a top hat on a snowman. The snowman comes to life and tells Perry "Wintertime's fun. Follow me!" A loud crash is heard, and the poor snowman's nose rolls over to Perry, then Perry is next shown exiting the Agency's elevator into The Agency Christmas party, still holding the carrot, which Major Monogram later eats.
