add summer crabs

I don’t like the Hermit crabs being replace by the summer spider and the cave spider but I think that the crabs is perfect for the hermit crab like for example the sand crabs can become clam hermit crab

and the mud crabs can become the nautilus hermit crab

and finally the royal crab can become the conch hermit crab

but for the summer spider they can be replace with the spider crabs
