I Want My Hat Back in Japanese ("Doko Ittan")

The simple illustrations add a lot of character and wit. I wonder if the choice was to make the story more universally appealing or to focus on the humor.

The story takes a surprising turn at the end that made me think about how children interpret humor and darker themes. What was everyone's reaction to that?

His storytelling feels so unique and dry, yet engaging. I'm curious whether this was influenced by other artists or a conscious creative choice.
