Easy-to-find basics like a hooded sweatshirt and sweatpants are the starting points for this fun Halloween costume. And a clever notch at each shoulder allows this penguin's wings to lie just right.

Cut 2 wings and a belly from craft foam. You can download these templates for all the penguin pieces. Cut a triangle from the top of each wing, then tape it closed with the duct tape; this creates a shape that hugs the shoulder.

Cut slits and thread the bow tie through them.

Cut out the beak, 2 feet, and 4 circles for the eyes from craft foam. Fold the beak in half lengthwise, then use double-sided foam tape inside the point to secure the fold.

Tape the small circles onto the big ones.

Attach the beak and eyes to the sweatshirt hood and the feet to your child's shoes with double-sided foam tape. Secure the bow tie around your child's neck and adjust it to fit.
