Kiss enough frogs, you'll eventually find a prince.
We approached some of the early phrases with images in mind, but we also considered some of the subjects of which kids are afraid. While boys revel in collecting slimy creatures, frogs seem to be almost exclusively something little girls don't like. This is not necessarily true in a modern world, but it's likely why fairy tale princes were turned into ogres and frogs.
This is for all the young girls who aren't afraid to turn over a few rocks to achieve their dreams. It doesn't even have to be about a boy. Your "prince" might be winning first place in the science fair.
