Quick 'Delightful' Mobile Game Needed

I'm in a competition that requires me to create a game with the theme of 'Delightful'. Since I have only a day for this task, I need a mobile game that fits the theme and is ready-made and reskin it.

Ideal game details:
- Developed for both iOS and Android
- A Casual genre
- Must be 'Delightful' in theme

Please send me any mobile games that you have ready and feel would be a good fit.
