ESPIRAL

ESPIRAL is a screamer video created and uploaded onto YouTube by a user Maignofe in 2017.

The video starts by showing a GIF of a spinning rainbow spiral, hence the title, the hue subsequently changes at 33 seconds, then suddenly, a picture of Pennywise from [Wikipedia:IT] pops-up along with a girl moaning.
