King Ka-thunk's Castle (known in English PAL versions as King Kathunk's Castle), or World 5-Castle, is the fifth castle level of Super Mario 3D World and the ninth course in World 5. It is unlocked via completing Searchlight Sneak, and its own completion frees the purple Sprixie Princess who builds a Clear Pipe to World 6.
This level starts on a platform with some Ka-thunks nearby, with some ? Blocks in sight. After navigating past some Chargin' Chucks and moving platforms, a nearby Warp Box takes the player to an area with some more Ka-thunks and the Checkpoint Flag. The player now needs to avoid Ka-thunks that come out from crevices in the wall, as well as more Chargin' Chucks. A nearby Warp Box brings the player to King Ka-thunk. After his defeat, a Warp Box transports the player to the purple Sprixie Princess and a Goal Pole.
