For the Camera Glitch, go to any sidescrolling level (Not battling area) in Adventure Mode as Jigglypuff. Break Jigglypuff's Shield and keep pausing the game. The Camera should focus on random parts of the level and the Camera will sometimes stay distorted when you resume the game. To control Nana, do a taunt and hold up on the Control Pad. Nana should still be doing her taunt. Then start Popo's Shield up. Then Nana will start up her Shield. Popo's breaks first. So stop holding up the Shield. Now try moving. Nana will be moving instead of Popo. You can only move Nana a little away from Popo. Try getting Popo frozen, asleep, or stunned. You will have more control over Nana.
