In 2005 we met the Chopper Droid, and a few years later we met Chopper the Clone Trooper.  Now meet Chopper the Astromech Droid, new for this year's upcoming animated Star Wars Rebels.  Based on Ralph McQuarrie's concept R2-D2, the little guy will also be an action figure later this year.  Click here for more - he's hidden in the gallery.
