He can be found in Chapter 3-2 and go down a warp pipe. Once inside, defeat all the enemies and a box will appear. Note that he will only follow you if you are playing Bowser. He can be used to ground-pound. He can be used to knock fruit off trees in the Overthere. He can also be used to push posts into the ground. By using Thudley to Pound Pound in mid-air, immediately cancelling the move, flipping to 3D (or 2D if already in 3D) and repeating the process, one can glitch the game to let Mario infinitely jump.
