Ghoul Medal

The Ghoul Medal is an anomalous collectible that can appear in Super Mario 64. It is often describes as a token of some sort with a Boo or skeleton engraving on it. It is usually associated with Big Boo's Haunt and Big Boo's Forest. It was believed to exist due to a sign found in Big Boo's Haunt that says: "You Don't stand a ghost of a chance in this house. If you walk out of here, you deserve... ...a Ghoul Medal..." Though some believe this is a play-on-words on the term "gold medal", some personalized copies have the Ghoul Medal as an actual unlockable item. When collected, it usually displays the animation when the player grabs a key.

Ways To Unlock
There are several ways to unlock the Ghoul Medal in several personalized copies. These include:


 * Using a Crazed Crate to clip out of the cage the course is inside of.
 * Finding it in Big Boo's Forest.
 * Getting on top of the mansion before the first mission is completed.
 * Unlocking a door in Big Boo's Haunt that had the Ghoul Medal in it with a Big Boo's Key.
 * Finding it in the Ghost Ship.

Giant Boo
Several copies have a supposed Giant Boo boss fight that unlocks the Ghoul Medal. It is usually a Boo twice the size of a Big Boo, and usually takes 10 hits to defeat. It's appearances vary, though it is often found by clipping into the mansion using a Crazed Crate.
