Wapol's Omnivorous Hurrah is the fifth Cover Story created as a side story on the title pages of each One Piece chapter. The story can be set between the events of Drum Island Arc and the timeskip.
Having been propelled onto an unknown island by Luffy, Wapol experiences life as a homeless man for the first time. Eventually, he uses his Baku Baku powers to create unique toys by fusing different objects together and begins to work his way back up the social ladder by selling these toys to children. In the end, he opened his own shop and married Kinderella.
On an unknown island, the landscape has been marred by someone taking bites out of it. That person is revealed to be Wapol, currently sporting a tree head after eating one. Wapol then eats a gas lamp, annoying the nocturnal animals at night, and then a bench, scaring away unsuspecting people trying to sit on him. Finally, Wapol snaps and starts eating the entire town for dessert, which results in his arrest.
Wapol, meanwhile, escapes arrest and ends up in a dump with a dog that constantly pees on him. Wapol tries to make money by selling matches, but nobody wants to get near him. Wapol ends up eating broken toys under a bridge, completely destitute, with nothing left of his former life as a king. However, while munching on the junk, he ends up using his Baku Baku Factory technique to create combined junk toys. The island children love Wapol's new toy creations, so Wapol starts selling them for a profit. Wapol's toy booth booms in popularity, and quickly expands.
One of the children brings his new toy and shows it to his scientist father, who discovers that the toy is made out of an unidentified, powerful alloy. Wapol was then thrust into the limelight for this invention, which he dubbed "Wapometal." He managed to become rich enough to build his own toy shop, and then an entire factory, and even an entire conglomerate. He then married a beautiful woman by name of Kinderella. With her and his new pet, Hakowan, at his side, Wapol has become more rich and powerful than he ever was as a king.
During the timeskip, Wapol and his wife founded their own kingdom. In addition, during the time skip, Franky was able to use Wapometal to advance his own technology. Perona acquired one of Wapol's toys and had Hogback create a zombie based off of it.
