The Game Boy Camera is a peripheral for the Game Boy by Nintendo that allows one to shoot photos with it. However, there are also mini-games included in the cart itself, namely Space Fever II (a shoot-em-up), DJ (a music creation tool), Ball (a juggling game similar to the G&W games) and Run! Run! Run! (a sports game where you race against the clock, which needs to be unlocked first).
ThunderAxe31 plays through Space Fever II to unlock the hidden mini-game Run! Run! Run!, then clears it in record time.
