Mario and Luigi: Bowser's Inside Story

Heal Bowser's back without Having to Wait for the Alarm:
When you enter the Lumbar Nook and dig into the broken bone,
you have to wait for about 5-10 minutes for the alarm to go off,
and you can't do anything else until it rings. However, if you
press ABXYLRYXBA in the exact order, the alarm goes off instantly,
regardless of how much time it's been!

Alternate Ending:
Beat the game with Mario, Luigi, and Bowser all being at least Level 40.
