Description: A sticker book that helps build good tooth-brushing habits in children! Kids can experience how cavities form by placing stickers. Every time they brush their teeth, they can add a brushing sticker to the Chika Chika Dispatch Chart. Cavity germs have arrived by UFO to attack the Healthy Kingdom and turn it into a terrifying Cavity Kingdom. If left unchecked, the once-white teeth will all turn black and rot—and once a tooth decays, it can never become white again. But there's no need to worry! We have the amazing 'Chika Chika Squad' to protect the Healthy Kingdom. They say getting kids to brush their teeth can be just as challenging as getting them to eat! If it's time to help your child develop the habit of brushing on their own, give them the gift of 'Chika Chika Ttakttak! Sticker Book.' By placing 338 stickers and becoming a brave commander who deploys the Chika Chika Squad to defeat the cavity germs, your child will transform into a healthy kid with great brushing habits before you know it.
