Screechyphobia is the fear of being screeched by Four.
- Everyone in BFB has this fear excluding Four himself.
- it exists irl for real
- In the show, a tape recorder plays the screech, but no one was scared, except Donut.
- Four's screech itself is from Freesound (a sound database that anyone can upload and download), available under the Creative Commons Zero License. Here is the link to the uncut sound.
- According to Cary, it is possible to build up a tolerance to Four's screech.
- In real life, Four's screech must be louder than 120 decibels in order to cause damage.
