It’s about a crab who’s shell was too small and was trying to find a new one. He searched and sometimes made new one, but they either were too smelly or too small. Then one day he found a blue boot. He made it as his new shell and it also scared the seagulls away from the other hermit crabs.
Hermit Crab has outgrown his first shell, and, as hermit crabs do, he must look for a new house. Nervous and a little frightened, the crab plucks up his courage and finds a shell that's big enough for him. The only problem is that it's very bare.
