Not every monster character is a scary one, so if you are leaning towards a cuddly monster character for Halloween or a costume party, consider some of the characters from the Disney Pixar film "Monsters, Inc." Mike Wazowski is the round, green, one-eyed monster who is the assistant of "top scarer" Sulley, the furry blue monster who scares children for a living. Reuse items such as an old exercise ball and newspaper to create a Mike Wazowski costume.
Cover an exercise ball completely in cling film. Secure the wrap with tape, but avoid placing tape directly on the ball.
Tear newspaper into strips about 1 inch wide and 12 inches in length. Pour white glue into a flat dish and saturate each strip to create paper mache. Cover the entire ball with the strips. Add a 1/4 cup of water to dilute the glue if needed. Avoid covering the opening used to inflate and deflate the ball (you will later use that opening as an arm hole). Cover the ball with four to six layers of newspaper strips and allow it to dry overnight.
Sand the rough edges of the dried paper-mache ball and cover the entire ball with glue. Allow it to dry for another two to three hours. Mark where the armholes will go. Use a pair of scissors to cut out the holes in the paper mache without cutting into the exercise ball. Deflate and remove the exercise ball through one of the arm holes. The cling film will allow for easy removal without injuring the ball itself, though the cling film may remain inside the costume.
Cut an opening out of the bottom of the paper-mache ball, large enough to pull over your shoulders. Cut an opening in the top of the piece for your head.
Paint the entire costume light green. Allow it to dry, then paint Mike's large, round eye and toothy grin in the centre of the costume with white and green paint. Use images of Mike to get the eye and mouth correct.
Put on green leggings, a fitted, long-sleeved green shirt and green gloves and shoes. Fit the costume over your head and through the arm holes. Make adjustments as necessary to the openings, so the costume fits comfortably.
If desired make the eye separately from paper mache, then paint it and glue it to the front of the costume.
