In the Nintendo Comics System, the Apook Corporation ("Koopa" spelled backwards) is a giant corporate conglomerate that sells and produces most of the commercial products in the Mushroom Kingdom. It is implied that it is in some manner run by Bowser for the citizens of his Koopa clan, though Mario and friends seem to use Apook products as well from time to time. The biggest retailer of Apook products is the Koopamart. It is mentioned by Mario in Tanooki Suits Me, tricking Wart into believing that the art from the Royal Art Gallery that was sold to him by Bowser were products of the Apook Corporation, and would turn back into worthless raccoons in ten minutes. It is also referred to in The Revenge of Pipe Ooze! as the owner of Burger World which is known for selling things like Slime Burgers, Lard Fries, and Mold Shakes.
