In the mall they are selling these hermit crabs to children. Nothing strange about that, except they have painted the shell. Some are Superman, others are Batman etc. I cannot help to think it is a little bit strange and tacky, and do the children who buy these, understand it is not a toy, but a live animal? And is the crabs who has Hello Kitty on their shell being bullied by the Superman and Batmans, and how do they know which are guy crabs a girl crabs...?
