There are NO hermit crabs in this box! The picture is deceptive. Had I not carefully looked this over when it came in, my niece would have had a playhouse with no inhabitants for Christmas. Toy manufacturers need to be a bit more forthcoming about things like this, especially for those of us who mostly shop on-line and are not accustomed to buying for children! I get it -- they want to sell lots of little creatures to live in this house, and we adults are expected to shell out for them (no pun intended). That's OK, little ones exhibit more glee over bits of colored plastic than the average adult does over anything short of winning the lottery. Aunties like me love to see that excitement in them, so sure, we're going to buy the plastic -- but we're going to be far more likely to buy it from companies that don't set us up for a Christmas disaster! Rating? I guess I'll give it a four, but only because my niece absolutely loved it!
