Imagine a giant, chubby water pillow with flippers that decided it wanted to live in the ocean. It’s like a blob of grayish jelly that swallowed a beach ball and just rolled into the sea. Its face is a bit squished, and it has big, sad eyes as if it's always contemplating life choices. When it swims, it looks like a slow-moving circus act, flopping around and occasionally popping its head out of the water like an overcooked sausage. If you catch it on land, it’s basically a sleepy potato that enjoys lounging in the sun, snoring loudly and flipping sand onto itself.
