Those things are ALIVE? (I always thought they were just a type of seashell bc of animal crossing)

They're very pretty when alive. There are red, purple, and brown ones on the beach near me at low tide. They have tiny little feelers/feet on the bottom that helps them bring sand and food into their center mouth area, and move them along the ocean floor.

Here's a cool little video about them.

You do know all seashells once had a living thing inside, right? Corals are living organisms too

I think they mean like living in like a snail vs living around like an urchin

Maybe, but their phrasing kinda shocked me. I actually know sand dollars thanks to animal crossing too, but learned more about them once I got older. They're actually a type of sea urchin!
