I’m pretty sure Kai wishes we could spend all our money on wood for a treehouse. Of course, we’d also need a tree…
Flower Bot
Every robot should have a pocket for flowers. 🌹🌷❤️
Fan
There was a LOT of drama around this fan (Kai lost the fans he’d made during his first day of camp, so there was quite an epic meltdown). This is the replacement fan he made after getting home. 
Map of the neighborhood, with various people’s houses labeled:
Book: “Joe Has the Cat,” pirate ship, car driving through time portal:
Person drawing, hand holding a love letter, a really big number, a person doing kung fu:
Excerpts
Kai is starting to sound words out and write them himself. 
Translation: Meanwhile, undersea…jellyfishhhh. (Replace the L in Meanwhile with an M and it’ll make more sense.)
H! = gasp
Translation: Bump bump bump…<gasp>…(bad guys approach)…<gasp>…Meanwhile…
Y Kai Zap
Some of Kai’s latest drawings. He’s big into illustrating “zap,” I love you, and, his latest message, “Y Kai zap.” Why indeed. 
The last one includes three puffy clouds above “Y Kai Zap,” houses, and I ❤️️U.
