Children's book with a girl who has to paint flowers
Okay I read this book in elementary school on the 2010s on Kindle. I don't remember much about it. The main character was a little girl, and I almost want to say she couldn't remember her name and part of the story was her trying to remember her name? She was on i believe some kind of island with a dictator ruler (a queen, maybe?). I think there were people who were turned into animals, i think farm animals like goats and pigs, and she and the animals were having to paint flowers on the island for the queen? There was also a character with some sort of name like Princess Coquichilita or something, I don't even know. I also believe there was some sort of hall of memories, and there was a jar of buttons which was somehow important. I'm sorry I know that's so vague, and some of the details might be wrong! This has just been bugging me!
