Why does Happy Hammer teach bad children?

The animation of Happy Hammer should be child-centered at first, but I have to spray it. The content is a little naive. I wonder what they think. Even if they play with stalks in moderation, almost every episode uses rotten stalks. Some plots are strange, out of context, incoherent and exaggerated. But it's a little too exaggerated. Even after reading it, the whole person is stupid. The music used is ignorant, and the marketing number music used.
