Lisa as a ponygirl (or maybe even her reaction to Allycat taking her to a ponygirl stable and then suggesting it) would work for me too, but I'd rather see ponies that are clearly dressage (with feathers and stuff), draft (various ways of doing this but some sort of cart/chariot/selkie harness), or show-jumping (much cleaner lined and less decorative tack, remember they'll be racing against the clock).



If this sets you off at a total tangent to your planned script, you're welcome to use it.
