My son always make snakes out of clay. He pastes it on the wall or apply it on things like legos & cars & monster truck. One day we made pretend exhaust pipes using clay on each car. But the end result is ugly - always. So much clay gets into his nail. Can't get rid of clays which gets into toy's corners. I will show your creative beautiful nest to him & help him understand on how to play with clay properly. Hope he'll get creative. Keeping my hopes low as you know, boys will be boys.
