Mini Lego Heist

A few years ago one of the keepers at my former institution gave me a mini lego zookeeper that I kept on the dashboard of my car. When the lego keeper's banana went missing during my last car inspection I figured that it had fallen somewhere in the car never to be seen again. But then just yesterday the lego chimpanzee went missing just after servicing my car. I have ordered a replacement from Amazon, but this leads me to wonder what it is about mini legos that seems to attracts car service men!
