In Glitzville, when you make a "comeback" after you beat Rawk Hawk the first time and fight your way to the finals, one of the spectators will, instead of cheering "Gonzales", or something to that effect, will cheer "Jumpman! I mean, who?" Jumpman was the original name for Mario before he was called Mario, IE back in the days of Donkey Kong Arcade.
Missed any Tattle Logs, particularly boss logs? They are not gone for good. Check Professor Frankly's yellow trash can. You will find Tattle Logs thrown away for bosses and other once-only enemies. The log will only appear in the trash once you've gone past the last possible point to Tattle that enemy.
If you use an FP-Consuming attack outside of battle(Such as a Spin jump) and get a first strike, you will use that move automatically in battle without using any FP at all.
For every 10 levels you complete in the Pit of 100 Trials, you'll earn a new badge or other item
When you get an important e-mail (ie; the e-mails from Princess Peach), wait a couple of seconds and you will hear music from Super Mario World.
Get both the W emblem and L emblem and put them on, Mario's hat and shirt will be purple and his overalls will be purple, just like Waluigi.
