色が変わるお風呂絵本 - どろどろディノくん

The pages actually turn white when you wet them, which kept my toddler fascinated through the whole story. We've read it three times tonight alone.

My nephew loves dipping his finger in water to clean the dinosaurs, and the colors fading back is such a clever detail. It's a sturdy little book that actually keeps him engaged during bath time, which is rare for us.

My toddler is obsessed with scrubbing the muddy dinos clean with her finger — the water-activated color change is instant and keeps her engaged through the whole story. The pages have held up to repeated splashing without any tearing, which is a huge win for bath time.
