- Mario Bros. theme song
Notice: You do not need an SD card or music for this trick. Go to the 'Sound Channel', and tap 'Record And Edit A Sound'. Do not touch anything on the DSi. After approximately a minute, the Mario Bros. theme will play. At the very end of the audio, it will begin playing a random audio clip from your library (not your SD card).

- Mario coin mini-game
Notice: This trick requires at least one song file on the console that can be played in 'Music'. While in the 'Music channel' on the Nintendo DSi, begin a song, then instantly pause it. Look at the bottom screen's shoulder instruments. Scroll through until the 'No sound' icon is displayed on them. Push Up repeatedly until the screen with Mario running appears. Push 'Play', and use L and R to make Mario jump. See how many coins you can collect within your favorite songs. Notice: The shoulder button sounds need to be set to 'None' so that the audio does not become distorted; however, you can still play with them if desired.

- Parrot
The parrot records sound at the begining screen. If you wait awhile it will begin to repeat some things and the sounds that the mic hears.
