Why aren't there tons of Elephant and Piggie crafts and activities to be found on Pinterest and the greater internet? Who knows? Maybe it is because Mo Willems hunts people down who make resources based on his books and feeds them to the Knuffle Bunny.
Anyway, one activity that is out there is to make a nest and tie it to your head like a crazy person. This is apparently based on 'There is a Bird on Your Head!' But the birds from the book are nowhere to be found. So I drew them, got a paper bowl, shredded some brown paper, got some pom-poms, located a piece of ribbon, glued the birds and the paper into the bowl and tied it on my head…Like a crazy person.
Here the birds are. Free.
