I have found something very interesting in Kid Icarus: Uprising! It all has to do with cutscenes: In Chapter 18, The Ring Of Chaos, when the screen shows Pit as a ring on the black background, if you move the Circle Pad, the ring will shake a bit for each Circle Pad slide! It kinda reminds me of a move in the Kirby series...
The best part is: In ANY cutscene, if you press and hold any attack button (Default: L, A, B, Y, +Control Pad Up), the screen will zoom! And you can even control the camera with the Circle Pad!
Try it out guys, it can lead to funny and hilarious stuff!
