the secret boss of Disc 3. You have to walk to the edge of the balcony at Castle Murica, then enter the Konami Code 3 times. It should warp you to the secret Wal-Mart stage. Head to the upper left section of the stage, where you'll see the fridge section. Press E or X to open the door, then press it again to enter the fridge and close the door. A secret elevator will trigger, taking you to the Disgruntled Employee Lair. That's where you'll find Aye-Browes, the Glarer. Beating her will give you the Wal-Mart t-shirt, which increases your chances of a successful intimidation by 200%.
You're welcome.
