On that subject, I've got a handful 'o tuts on my freebie Geo site if you want.
No creatures I'm afraid, just simple things.. but the subject isn't necessarily that important, still serves to get peeps familiar with some of Wing's tools & interface. And they're mostly written in an almost "script form" (e.g "Right Click > Extrude to 0.5, then Right Click > Scale Uniform up 200%" etc.) so very newbie friendly, with pretty much all the steps anyone could need.
Maybe skip the pumpkin tut... it's is the oldest, and the hollowing out part could be done easier with the 'Intrude' command (which wasn't in Wings at the time the tut was made) rather than how I did it there.
The mushroom one is pretty good 'n current though, biological-ish modeling.. and touches on tweak-magnets which you'll definitely want to know about for animal modeling.
