Sorry, but that's hilarious!! That's totally something that would happen in my house :-)
First off all, congrats on a successful pee pee! I would leave the potty chair somewhere accessible and let her approach it when she's ready again. Next time she's ready to try, limit the audience and celebration to just you and her. Make it more of a quiet time thing...maybe leave a couple favorite books by the potty and let her read while she sits on It. I'm sure you didn't scare her off it forever :-).
I did the 'reward the pee pee' method when my daughter potty trained. Most people say give an M&M or small candy, but my daughter doesn't really like candy or sweets. So I bought a bunch of little things from the dollar spot at Target and let her choose a surprise out of the bag every time she peed for the first week or so. It was a little pricey, but I figured it was cheaper than buying diapers. Once she got the hang out it, I would distract her after she peed so she wouldn't immediately start thinking of choosing a prize. She 'weaned' ' off the prizes pretty quickly.
Good luck!
