wall.e the game Easter Egg - Pixar reference

At the part where you have to pass the fat traffic, you will see coins outside the window. Beat the puzzle to get outside. Outside kill the two bots that shoot out lasers. You will see a wall with an electrical current running through, and a cellphone dispenser. Make 3 cubes (to balance them on your head) and throw them at the 3 red squares. The current will flow freely to the end and will turn on the light. A doll will come out. The doll is a well known character from Pixar: Buzz Lightyear. Wall.e also comes from Pixar. Enjoy!!
