From the game Super Mario 64 (Japanese version)
First, you must have around 124 stars and collect a 1,000 coins by avoiding Bowser's fire breath. In Bowser in the Dark World, it's possible to get a thousand coins. If you do so, the life counter will change from "4" to "M25". The green letter M means the minus sign, known by the player. They will notice it is negative. If the player loses his health, the life counter will go up. If the player gets an extra life, the counter will decrease.
|Warning:||If you meet Yoshi on the top of the castle, this will lock up the screen. The best way to get rid of the M is to have M128 lives so that Yoshi can give you more lives.|
