Oh that’s exciting! I hope he loves it as much as I did!

I can’t speak for the revised version, but the original was super engaging when I was a kid (probably got it around 95 or thereabouts, so somewhere in the 6-8 range), but not so serious or complicated as to distract from the whimsy.

It’s one of many things that led me to a deep intense curiosity about the world around me!
