I created these two height charts of Kitty Claws and Holidog to be sold in the Holiday World & Splashin' Safari gift shops. They can be stuck to any smooth surface, and are removable so parents do not need to worry about damaging their walls. Kids are able to easily measure their height next to their favorite character and can see when they are tall enough to ride the next big ride.
Note: To ensure accuracy and branding, I took these characters almost exactly from photographs. They are not my original ideas. All rights belong to Holiday World & Splashin' Safari.
