Animated header for website

A new website (not yet built) will feature an animated header. there will be 4 headers that we can change when needed. 1. The goat (attached document) walks along, turns its head and winks 2. the goat walks along then does some droppings (in a little pile), smiles then continues 3. The goat walks along and then faints - see this youtube video to see real fainting goats. [login to view URL] their whole body goes stiff. 4. goats walking along together across the screen. The size should be for a 700 x 200 (if it needs to be a bit bigger please let me know and we can agree a size).
