Wendel is a mouse and an inventor/engineer. He lives in a workshop and invents (i.e. builds) things all the time. If something doesn't work, he just chucks it down the chute and it ends up on a gigantic scrap heap outside.
If this book appeals to you then you might also like to look at [[Baby Brains and RoboMum]] which has a similar message that automation can be taken too far!
