The Schmuzzies are main characters in The Upside Down Show.
The Schmuzzies are small, furry creatures living in the apartment along with Shane, David and Puppet. They can only speak "Schmuzzish," a language consisting of English words with a "sch" sound added to the beginnings of them. David is capable of understanding them, having studied Schmuzzish earlier in life.
The Schmuzzies come in a wide variety of colors and shapes. Most of them are spherical, while some are oval-shaped. All of them have two black, beady eyes and a large black mouth.
The Schmuzzies appear in every episode of The Upside Down Show. They debuted in "Movie Theatre" and were last seen in "Mini Golf."
