The princess's sprite grows after each new level is cleared successfully, I believe.
Edit: or maybe it has to do with giving her the eggs, that would make sense... if so, it's not after every egg.
After reaching the last level, you can continue to upgrade her. Every 100+ Hit points results in a larger sprite. That said I currently only have two larger sprites past the level 5 nursery.
Oh, that's hilarious because I gave up on that after 9 more seeds after the last level since that's the max you can buy with 99 gems
