Life isn't so complicated for children. They have more time to think about the really important things. That's why I occasionally moralise in my children's books in a way I wouldn't dare when writing for adults. ↗
There are things that I invented - the creaky geriatric robot that is always grumpy, for example, or the little wheelie guy, he's not in the Hasbro lore. But kids love that stuff - this little guy as a pet on a chain. They gravitate towards it. ↗
