The Cat in the Hat in one of the most iconic children's stories of all time. If your son or daughter wants to capture the fun of this story in his or her Halloween costume, then the Dr. Seuss Deluxe Thing 1 or Thing 2 Child's Costume is the perfect choice for them. With this costume, they can choose to be either Thing 1 or Thing 2, as it features detachable numbers that can be applied to the front of the red jumpsuit. It also includes a blue fake fur wig, and gloves attached to the jumpsuit. When the Cat in the Hat comes to the little boy and girl's house, he unleashes Things 1 and 2, who make a huge mess. Hopefully your children will be a bit more subdued in their costumes.
