Crab update

My son (nickgoatt17) would love a crab update. The crabs would be able to eat fish, kelp, seagrass, and sugar cane. They would be able to spit sugar and dried kelp out of their mouths. There would be four types of crabs dependent on location: swamp crabs, pond crabs, beach crabs, and underwater crabs. The crabs would drop crab shells. With nine you could make a crab claw. If you have a thing in your crab claw, it would give you four extra blocks of reach. They would also drop crab meat. The pond crabs would be brown. The swamp crabs would be black. The underwater crabs would be blue and red. The beach crabs would also be blue and red. You could tame them by using kelp and sugar cane or sea grass.
