Try the Magma Maze, which can be reached by jumping into the wall of the room with Sand Land (if you fall down, jump back up), and then in the main room (you'll know it when you see it) go to the top left. Or, ground pound under the cloud painting next to Tall Tall Mountain.
Yes, the last storyline is in Bowser 3.
