I hate the stats for the thylacine! Why was it made like that, it isn't a magical beast, its a real animal? It is known alsoas the tasmanian tiger, and is nothing like the one posted here. Why?
you'll find that quite a number of D&D creatures were created as magical/fantastic monsters, having the same name as real world animals. the thylacine, by ed greenwood, is one of these. why he chose to do it the way he did, i don't know, but i've always liked it. now if you just want another type of feline animal, it's easy enough to modify a tiger or lion's stats slightly.
