Create a set of fun, quirky 2D characters and small sets of animations for each character

Hello! We are building a fun learning to read app for young children and want to include a set of fun characters that the child will interact with. The characters will be simple and inspired by letters/sounds. The animations will be be quite simple as well. Each character will be able to a set of actions (scratch self/eat/sleep/burp). To get a sense of the aesthetic, please look at our early version app. https://bit.ly/giffdribble We really want someone who can make playful/naughty/quirky characters that kids can love. Please share relevant samples and mention the name of our app, which we linked to.
