You get a crawling animation, a pose on all fours and a lick paw variation of the all fours pose. You also get a sample AO config notecard to show you how they work together. To see them in action, take a look at this movie on YouTube.com:

I plan on making some variations for tall avis so they don't float above the ground--these animations were made with shorter avis in mind.
