So IO have consulted the expert (my Nephew, yeah he smells like a boy too). He surprised me by saying that some of the best things he has gotten have been from me. Which was sweet. He loves doing origami! Which is cheap and fun to learn. I also like to buy the long balloons and we learned how to make balloon animals which would be fun for even the smaller kids and the older child could help them. I also taught him how to do face painting (we were trying to entertain his little brother) Which led to him designing "tattoos" and later led to the comic book drawing.
He also really enjoyed the card tricks book I got him which he tries to use to swindle me for money whenever I see him. And i also don't recommend the marshmallow shooters. LOL Good luck.
