Bowserstopped inhaling after seeing that everyone had been swallowed into his gut, chuckling darkly to himself after. "That'll teach you little rats. Nobody messes with the Koopa King! BWAHAHAHAHAHAHAH!" He pumped his fists into the air, triumphantly, and, after having calmed down, charged headlong towards the door of the COWH. With little to no effort, the door gave way, and Bowser was inside the back entrance, which was essentially at the end of another long hallway. Bowser was able to see into forever. "This place is huge. It would make a GREAT castle!" He said, before he started walking around to explore his new found territory.
Meanwhile, in Bowser's gut, the inhaled group was dropped into his esophagus, which, for some reason, wasn't a straight drop into his stomach.
