I know that in the PS2 game, you could lure Mr. Luntz into the basement at School time, first by breaking the School Store window (hide in nearby locker), then by shooting him with a Slingshot, Spud Gun, etc. Then dashing through the basement door, My Luntz will chase right by you and wind up down the steps in the 'tunnel' leading to 'The Hole'. He will just stand there with his back to you, making an easy target.
