You can up an Android collectible figure's coolness factor a trillion-fold by making it more robot-like. Make your little bot react to sound, turn its head, put on a light show, and send out Morse Code messages with these instructions.

Mini collectible figures can add some cheer or whimsy to your day, but imagine how much brighter your day would be if those figures were mechanised? If every co-worker interruption was met with a series of flashing lights and beeps from your 3" Android collectible, perhaps you would be less annoyed. (Perhaps not. It's still a cool project.)
The engineering directions from Instructables user tanabata can also be adapted to other types of collectible figures, as long as there's space for all the parts.
