You're both right about him hunting for something...but it's not the key. He was told that I needed his help to clean up the playroom...to find a certain quantity of a very specific item that I "accidentally" dropped many of around the playroom. A few hints... Hint #1: You can see the item he's looking for in pic 1 and pic 5. Hint #2:  He obviously can't use his hands, so I had to provide him with another way to collect the items. Hint #3: There are certain things I used to create obstacles to interfere with the method I gave him to collect the items, such as the metal chain you see laying on the floor. With those hints, any other ideas on what I have him collecting, the method I gave him to collect them, and how the obstacles could interfere with that?
