Schmoo is a floating disembodied head with a grotesque appearance that flies erratically, careening around the room to attempt to hit the protagonist. It does a surprising amount of Dark damage with each hit and can be hard to target. Most importantly, Schmoos drop the Crissaegrim, although only very rarely. Earning the Crissaegrim essentially makes the rest of the game very easy.

- Schmoo is the only enemy in the Forbidden Library based on a literary source other than The Wonderful Wizard of Oz. Its presence there suggests that Dracula's library includes comic books in addition to literary classics.
- In North America, this creature was called "Schmoo", which is likely a reference to The Shmoo from the Li'l Abner comics, created by Al Capp. The original shmoos are little white creatures shaped like bowling pins with legs, not resembling the bleeding, rotting heads that are Castlevania schmoos.
- In the original Japanese version of Symphony of the Night, this enemy was called "Kyū". It may be a parody of Kyū (which was an obake) from the manga Obake no Q-tarō.
- A similar enemy called Arabaki later appeared in Castlevania: Harmony of Dissonance.
