Does he have a nice set of blocks? Or how about Lincoln logs? (they still make the wooden ones, but as to how natural they are I'm not sure.) He also has a set of wooden stringing beads from Toys R Us that he likes a lot.
Toys R Us has a train table set under $200 that comes with a wooden train, my DS has it at Grandma's house and really enjoys that too.
