Invizimals due out for the Playstation Portable this November has you running around with a camera plugged into the portable searching for invisible creatures.

The game uses a form of augmented reality to locate creatures and then asks you to capture them with your PSP.

But here's the thing: Capturing them isn't always as easy as pushing a button. Sometimes you'll have to do other things, like sneak up behind one and yell at it loudly to scare it into your trap. Or, the case of this snake-like invizimal, whistle a specific tune to charm the creature to the trap.
