From the popular app Pokémon Smile, which helps children get into the habit of brushing their teeth, comes a mysterious and fun tooth brushing educational picture book. Metamo Color Rubbing and playing! Pokémon Brushing Teeth (メタモカラー こすってあそべる！　ポケモンはみがき), features a material that changes color with temperature and was used for this picture book.

The secret is that body temperature and frictional heat of touching and rubbing the pages can be used to erase the actual stains on the teeth in the picture, making the reader want to try again and again. In addition, cute Pokémon drawn by popular illustrator Kanahei will cheer you on and praise your work, saying, "You did well!" The content of the book is supervised by the Japan Dental Association, so parents and children can enjoy it with peace of mind.

Comments from a representative of Pilot Ink:
"We hope that children will experience the fun of Metamo Color changing and that this picture book will encourage them to create a habit that brushing their teeth is fun!"
