The Grump lives in a dark, messy tree hollow and could always be upset. For example, about the Kucks, that thin, red-haired wiggler! Every morning, it stands at his door with a gift and asks him, "Can I look at you today?" The Kucks thinks he is beautiful. Although a three-wish fairy appears to the Grump, somehow the wishes are never enough to make the Kucks disappear. One day, however, he steps out of his hollow and lets the Kucks look at him. And then they set off together. The Kucks hops, the Grump stomps. Together, they sound like a beautiful song. A book for readers and storytellers aged four and up, who know a Kucks or a Grump or sometimes are a Kucks or a Grump themselves. About the great wonder of friendship between different forest inhabitants.
