Leucrocutanized

Earlier today, I was looking through my Compact Edition of the Oxford English Dictionary -- which, I am sorry to say, I now cannot read without actually using a magnifying glass -- and I came across a most bizarre word: "leucrocutanized," which means, "uttered as by a leucrotta." What a delightful word! Of course, it's also a rather specific word and not one I'm likely to be able to use in almost any normal context.

Afterward, two thoughts occurred to me. First, unless I am mistaken, there are no OGC game stats for the leucrotta anywhere. If correct, I may have to correct that, as I've always been fond of these weirdo beasts. Second, the leucrotta, as you probably know, is based on distorted tales of hyenas. This made me wonder why it is that D&D included stats for both "normal" and "mythical" versions of so many animals. In a world with leucrottas, do you need hyenas too? I suppose it's to provide options and that's fair enough, but, having pondered it now, I realize that, if I do include leucrottas (or any other mythical animal-type monster), I won't also be including the real world animal on which they're based.
