Duckies/ducklings-game guide extension

I hereby propose to expand the already existing guide: https://docs.yellow.org/duckies/ducklings-game . The idea is to create a printable PDF guide as a flyer to be distributed that includes ICONS representing the various characteristics "eyes beak wings body head" , encouraging memorization using primarily paper (or video to pc / mobile) and then the trait value memorization as in an educational visualization/memorization exercise. N.B: introducing only a few traits that will be chosen by the development team as I learned that extensions of the traits are already underway
