Saw this on the Chinese news when my mom was watching it. It's a sculpture that's an amalgamation of movie BB with a Sideswipe head and some other bitties. It was stated that the sculpture is edible and made from both chocolate and wax. Sorry for the low quality pics. I just grabbed my phone and took two shots and sent them to my laptop.
... Haven't you ever heard of edible wax? It's used in almost all candies that we eat for that lovely sheen. It looks more like Bumblebee from the back, what with the "wing" arrangements. The tires also aren't really all that visible in the full body shot that I took.
