After having looked and unpacked all the Darth Vader and Yoda characters, he ended up only playing with this last minute find: a pack of Straws and Connectors.
He made a boat for he and his sister to ride in, complete with steering parts, then a fort, a race car, a castle, and is now focused on building the highest tower in the world. This has been going on for the last month and doesn't seem to be letting up.
I watch this in awe as we obviously much prefer for him to play with these imaginative toys. Had we known he would be so taken with this, we would have skipped right past the over-priced Hollywood paraphernalia.
