I did an internet search for words to describe Nils' youngest brother, Julius, and this is what I came up with:
Other words that would have worked are agile, bustling, chipper, dextrous, and most of all....energetic! But whatever word you use, I love that kid. He is one fireball of energy who's not afraid of anything! But with two older brothers, what do you expect?
I should also mention that Wolfgang has the most energy of quite possibly any adult man I have ever met. Maybe that has something to do with it.
Julius the Zealous had his skateboard on our trip to Strade....because when you're eight, you couldn't care less about historic buildings!
