A creature has been caught in a cave, and if you help him get out he'll give you a code to discover treasure!
You find a poor creature trapped on a video screen. It has fallen down a cave and got stuck. To free it, you need to squeeze its feet in the correct order, at which point it jumps out of the video screen and onto the wall behind it (with the help of a projector). On the wall behind it are written 10 digits. The creature hops on three of the digits, highlighting them. Those digits help you to unlock a box filled with treasure.
