Picture memory matching game for kids

This is what a business in United States was looking for in their app design

I'm developing a memory matching game for kids but need better/cuter graphics for it.
Currently the theme is Chinese zodiac symbols but you can do whatever theme you like.
I would like to have at least 15 images to choose from.
