The Bowling Alley is a place where people play bowling in Dimmsdale.
After Timmy wished up some monsters to play cards with, Crocker taped some in different parts of Dimmsdale and started a webshow about it, and Dad started to call him each week because he saw a monster in the house. Crocker used this opportunity to try and tape Timmy's fairies. But when Timmy wasn't in the room he went to check the wardrobe, where the monsters mauled him and his head fell in Mom's bowling bag, and she used him as the ball. The same series of events followed each week until Doug Dimmadome turned the webshow into a TV show.
