Gouache Ghouls

Gouache Gouls is the third stage in Grotesque Gallery.

Battleground
The level begins by spawning an Angel Fanboy and an Angelic Gory. When the base reaches 99% health, then all of the other enemies will spawn infinitely. Try all you want, but you will never beat this buffed bunch of angels.

However, there is a twist: If you stall the initial Angelic Gory for 66.67 seconds2000f, infinite Ms. Signs will spawn, allowing you to push them back and destroy the base.
