Here's a photo I found of the new 
Star Wars Twistheads available from Kinder in both Germany and Russia at the moment.  These new collectibles appear to be a game of sorts where you interlock their twisty heads and when pulled apart each character displays a number. Highest number wins I assume. You can visit the official Twistheads website 
here, and check out different video's for the product on their 
YouTube channel.
