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 she's technically a stuffed parrot, but I always know what she's thinking.

And right now she's thinking: Can we solve the mystery of the missing Blue Diamond and save the Museum of Natural History, before it's too late?
