でるとる is a special application developed by サンスター文具株式会社 that is designed to be used with their "ぬりえ" (coloring book) products. When you launch the app and load a colored "ぬりえ" pattern, the image comes to life in a three-dimensional way on the screen, as if it's jumping out of the page.

In addition to the interactive experience, you can tap the screen to enjoy various effects and sounds. Furthermore, you have the option to take a photo with the colored "ぬりえ" as a photo frame. This allows you to not only have fun coloring, but also create lasting memories with your child's artwork.

Even if you don't have the compatible "ぬりえ" patterns, you can still experience でるとる by downloading and printing the "おためしぬりえ" (trial coloring pages) provided on their website.

Please note that it's important to color within the lines of the illustrations and avoid using colors like black or dark brown that may cause compatibility issues.
