Bowser Rune

The Bowser Rune is an incredibly rare rune found in Shifting Sand Land in certain personalized copies of Super Mario 64. Usually, it takes the shape of Bowser's head, and can be collected in the pyramid.

Behavior
The behavior of the Bowser Rune typically varies, for some it can be used to unlock something, for others it is treated as 10 coins, and some people even report the Bowser Rune being either impossible to collect or just not doing anything at all after collecting. The few people who say that it actually unlocks something say it usually unlocks minor things, such as the pyramid's top opening up after collecting it. However, some reports say it can unlock anomalous sub-areas that have yet to be reported until now.

Unlockable Areas
As said above, certain reports say that the Bowser Rune can sometimes unlock anomalous sub-areas. Some of these examples will be listed here. Keep in mind that this list is not only growing, but there is likely no chance that finding the Bowser Rune in your copy will grant you access to these areas due to the location it leads (Assuming it even leads anywhere at all) varies far too much.


 * A sand maze under the quicksand
 * A new section of the pyramid
 * The 4th Floor (Report yet to be verified, and is highly doubted, so take this entry with a grain of salt.)
 * Klepto's Nest

Theories
Whether or not this was created by the A.I. or was unused is up for debate, and if it was unused the original purpose is currently unknown. However, some possible reasons is that it was possibly supposed to be the original way to opening the top of the pyramid, or that it was simply supposed to give coins originally. Regardless, this collectable is quite rare so it is very hard to find much about the Bowser Rune, other than a few reports.
