I'm not sure if this is against the rules to ask(read the rules), but I kind of need help.
I work in a children's group home that has 3 teens. I have gift ideas for 2 of them... But I'm stuck on the third. He loves putting toys together in a totem-pole type way (he will stick a sharp stick-like toy into the bottom of a me potato Head... Then put a dragon head thing that has a pointy bottom on top of Mr potato Head). He does this with a lot of toys.

Pic is a toy idea that looks great for him, except I'm not sure if the pieces would "stick" together well enough for him... He needs something durable like putting 4x4 Lego bricks on top of each other. Also, I think he is more creative than just staying one type of toy on itself.

Any ideas?

(Also he loves toys that are miniature people... He sticks peg-people on top of his creations too...even if it requires tape to make it stick xD)
