you can name the shark if you want, but you dont need to! they become more merged as they grow, so usually younger crybabys will name their sharks, but as they grow older they grow out of it most of the time. the older ones will keep their shark's name if the shark is smarter or more active than adverage.
so to sum it up, you or the crybaby can name the shark, but it is not required.
