There was a puff of magic and Beth and the prince were standing ankle-deep in the pond back to their normal size, and Beth had her fairytale dress back. (while the prince now had his old elegant attire.)
The only problem was that they were both frogs, although human-sized and anthromorphic. They were both bareflippered, as Beth's glass slippers wouldn't fit her big webbed feet. The prince's own leggings were torn at the thighs, exposing bare legs and feet below.
"This wasn't what I was hoping for..." sighed Beth, looking at her submerged flippers and wriggling her webbed toes.
