Waluigi is testing out a pair of binoculars that he has made, calling them "Waluigiscopes", and plans to use them to find Luigi's weaknesses. A pair of red and yellow Shy Guys arrive and ask Waluigi if they can borrow the binoculars. Waluigi refuses and shouts at them to go away, scaring the Shy Guys off.
