You enter the back room and it's filled with equipment and other items for up keep of the road runners. From road runner food pellets, medical charts, to examination equipment.
On the far side is a door leading out to the back of the road runner enclosure that you could not see from the outside.
Sitting on the table is a lab filled with computer and medical vials. Right next to computer is a gummy treat in the shape of the road runner from the cartoons.
You look around, no one is there.
