Imagine a squishy, wiggly creature with eight long, flappy arms that sometimes look like they're waving at you. This thing lives underwater and has a head that's sort of bulbous and can change colors like a mood ring. It has big, googly eyes and is often seen hiding in rocks or doing sneaky stuff. It can squirt out ink when it’s scared, kind of like a tiny underwater smoke bomb, and some people think it's super smart—like a brainy alien from the ocean! It’s basically a jelly-like magician that can squeeze into any tiny space and has a weird thing for shells.
