After fleeing for their lives, they inspect the box and find a strange cartoon paint can inside, which Wile uses to paint a tunnel on the wall, which they enter. Inside the tunnel, they find an image of a man pushing a boulder up a hill and a secret message to Daffy mentioning something called "Project Sisyphus", but are forced to flee an oncoming train before they can read further. The Acme operative spying on them is revealed to be an older, bitter Tweety, who reports to someone that they know about Project Sisyphus.
