Early Monsters - Name FORGOTTEN!!! (Patreon)

I don't know how I forgot this creature's name so completely. I remember filling entire doodle pages with them.

These gelatinous, stretchy little hat-like creatures were another silly, frantic, chaotic sort of being, but so much so that even the "jujus" couldn't stand them. Like gremlins, they loved to dismantle anything they could, squeezing into small spaces and using their prehensile, tapered heads as powerful tentacles.

Then, when danger struck, they'd just slingshot themselves away like a living rubber band.
