The Neo Bowser Castle is a giant ominious floating palace ruled by King Bowser himself and the final area in Mario & Luigi: Dream Team. On Pi'illo Island, it does not appear until the middle of the game, where it appears floating high above the island, until it is grounded and lands in the east, north of Somnom Woods and east of Mount Pajamaja. It can be reached by traveling north in the area between Mushrise Park and Somnom Woods.
