The Hermit Crab is a minor character in Finding Nemo.
"It's great carrying your home around on your back. Until a couple of bratty fish kids come along and snatch it off you! Can you imagine being made to play fishy-in-the-middle with your own home? It's a rough reef out there."
His home gets picked up by one of the bullies. He begs for the bratty fish kids to give his home back.
