Rustan isn't good only at agility. He also obeys other sorts of orders.

Today Carmen hid one of the toys under my layout in a space hard to get at. For some reason I thought to use Rustan to get it out, so I told him: "Fetch toy!" and pointed to the opening. He started by turning right when he should turn left, so I said "No, wrong way!", so he went and got it.

He didn't give it to me, but anyway he almost did what I told him to do.
