Did you brush your teeth? Hamigakirikiri is a monster that comes to you and asks the question. "Hamigaki" means brushing teeth in Japanese. If you didn't brush your teeth, they tickle you with sound "kiri kiri" until you brush your teeth. They help everyone to avoid cavities and keep our teeth clean and healthy.
