Use the remaining bottom half of the egg carton to cut out shapes for two wings and two feet. Paint the wings black and the feet orange. Glue in place.
Use another piece of the carton top to cut out two connected egg cups that have a triangular tab between them. These will be the eyes and the beak. Paint the pupils black and the beak orange as shown. Glue this piece inside the painted egg carton to make a face.
Lay your penguin on its back and fill its belly with pencils, crayons, and markers.
