Sherlock Bones and the Natural History Mystery

'Hi there, I'm Sherlock Bones. Who is Sherlock Bones, you ask? Well, I don't like to brag, but my trusty side-kick Watts says I'm the greatest detective in our whole museum. Don't you, Watts? Watts...? You might not be able to hear Watts, because he's technically a stuffed parrot, but I always know what he's thinking. And right now he's thinking: Can we solve the mystery of the missing Blue Diamond and save the Museum of Natural History, before it's too late?
