Just remix this project and make your own chalkface character. You can see my example in the project. Yeah that's right, you need to make it as a sprite. Once you remix this project, I might choose some of you guys chalkface character to be include as a next character in my next map of BBRMS which this character will called "Chalkface". This will be very interesting one since because the chalkface can transform into any random face everytime it appears on the chalkboard in each classroom.
