In Wendel's Workshop by Chris Riddell, Wendel is an inventor who enjoys making new robots to do his work around the house. Unfortunately, when his robots don't do their jobs very well, he throws them out on the scrap heap. In the end, the scrap robots are the ones who save the day. This story would be a great to use when talking about being persistent. Wendel gives up so easily when his inventions don't go right; he really shouldn't give up so easy each time. It is also good for talking about the fact that not everyone is perfect and we all do things in our own way.
