The Wivre

I found this monster in my book Giants, Monsters, and Dragons, which is really an excellent book and already reviewed on this blog. No real pictures seem to exist for this monster except for some screen shots from Final Fantasy (well, I didn't do an exhaustive search...).

Anyway, this creature is basically the French form of a wyvern. It is a dragon without wings and fiercely guards its treasure. You are sure to die from its attack... unless you do the one thing that makes it not attack you - strip off your clothes.

Yep, this beast will not attack anyone without clothes. This, I know is true, because I did an exhaustive Google search and not one nudist colony has ever been attacked by a wivre.
