What’s it about?

The story.

Rumple Buttercup has green skin, five crooked teeth, three strands of hair and one foot slightly bigger than the other, and he is quite sure that all of this makes him too strange to be seen. So he hides away in a sewer beneath the town, coming out only at night, with only his imaginary friend Candy Corn Carl for company. But a small chain of events slowly draws Rumple up into the daylight, where he discovers a surprising truth: nobody is bothered by his differences at all, and there is a place for him after all. Written and hand-lettered and illustrated by actor Matthew Gray Gubler, this offbeat, tender book celebrates individuality and the courage it takes to let yourself be known. Its scribbly, distinctive artwork and gently funny voice make it a reassuring read for any child who has ever felt like the odd one out, and a genuinely uplifting story about the magic of belonging.

Why kids love it

Rumple is odd and lovable, and the moment he realises no one minds his green skin or crooked teeth is a real relief. The scribbly art and his imaginary friend Candy Corn Carl make it feel like a secret world children want to climb into.

  • Being understood finally
  • Friendship and belonging
  • The underdog winning

Why parents love it

An offbeat, big-hearted fable about self-acceptance, written and drawn by Matthew Gray Gubler with obvious warmth. Its message lands without preaching, and its unusual look and gentle humour make it a lovely, giftable read for a child who feels different.
