"It is clear that sadly the Mokele-Mbembe variation is a dubious variation and should be avoided (unless you want to use it as a shock weapon in blitz/bullet)"

*) The Mokele Mbembe is certainly an odd variation and has an even odder origin. Mokele Mbembe was a river creature that pushes to the realms of cryto-zoology. Very similar to that of the Loch NessMonster, the creature is said to be an aquatic mammal with a very long neck.
