(This world is not given a name on the show. Puss 'N Boots is the name used here for reference purposes, and comes from the game on which the world is based.)
This world exists in several different time periods: Western, Pirate, Victorian, and even the 1920s/1930s. The residents of the world are all anthropomorphic animals, and a number of real-world landmarks exist here, including the Empire State Building, the White Cliffs of Dover, and the Statue of Liberty (albeit with a cat-like face).
Link and Kevin visit this world in "Once Upon a Time Machine" in an effort to recover Kevin's Power Pad and Zapper. They join forces with the mysterious cat Pero in an effort to catch Count Gruemon and Dr. Gari-Gari, who have stolen Kevin's items. Eventually, they succeed, but not before going through numerous time periods and perils.
