Happy Birthday! Here's something cool! An Easter Egg, if you will! Make your DS date your birthday and go into Pictochat. The first thing you will look at on your screen is the Birthday meesage in rainbow. The message will not be from anyone. It just comes up in a black and white box.
-Craig555 P.S; I don't think anyone goes on the PictoChat cheat area. P.P.S: Bye! P.P.P.S: Happy Gaming XD
Press the pen icon on the touch screen when you are in Pictochat on the DSi and keep pressing until it starts to flash different colours. When this happens draw on the touchscreen and your pictures will be drawn with a rainbow effect. This works only on DSi but the rainbow images can be sent to the DS Lite and DS.
