That is pretty cool. I have never heard of these characters before, but that isn't surprising given the distance. I like pieces like this where you can enjoy them as a child and then you realize as you get older that there was a whole different level to them. Even if it is just a joke that you need to be a little older to understand the full meaning.
This is what I am hoping for Smallsteps later. She can reread them by herself and get more out of it.
We started the Disc world series, but the language was far too hard for Smallsteps to grasp. I thought they were for kids, but the jokes in there and the language I would have struggled with even older than her, with English as a mother tongue!
Something you can come back to eventually though, so that is good.
