The Princess and the Frog (2009)

Tiana is a hardworking and striving young woman who has been dreaming of opening her own exquisite restaurant in New Orleans. Things started to go downhill when she crossed paths with Prince Naveen, who was turned into an amphibian. He mistakens her as a princess and asks her to kiss him, in hopes of breaking the spell. But since she is not a royalty after all, she ended up turning to an amphibian, too.
