Lava Rock Lair, otherwise known as World 4-Castle, is the second castle in Super Mario 3D World and its Nintendo Switch port Super Mario 3D World + Bowser's Fury. It can be accessed after completing Spike's Lost City, as well as having collected 50 Green Stars, and its own completion frees the orange Sprixie Princess who builds a Clear Pipe to World 5.


The player begins the level on a raised platform, with a slope that leads to an area with a Brolder, a Goomba Tower, and some Brick Blocks. Lava Bubbles are then found, along with a rotating platform. After the rotating platform, a Red Ring and a Brolder can be found, along with two more rotating platforms. After the player goes through a Clear Pipe, the player arrives at a long pathway containing several Brolders, Goomba Towers, and Brick Blocks. At the end of the pathway, a row of Lava Bubbles can be found in front of a Warp Pipe that leads to Boss Brolder. Behind the Warp Pipe is a Hidden Block with a Super Mushroom inside of it. After Boss Brolder is defeated, a Warp Box that leads to the Goal Pole and the orange Sprixie Princess appears.

Green Stars[edit]

  • Green Star 1: The player must stomp on the Brolder from starting position and throw it onto a P Panel while pressing the other one, and cross the now dropped bridge to grab the star. In multiplayer mode, another player can be used to hit one of the P Panels.
  • Green Star 2: After going through the Clear Pipe that goes through lava, the player sees a Mystery Box. The player must throw stomped Brolders onto two P Panels and step on a third switch to grab the Green Star. In multiplayer, two additional players can also be used.
  • Green Star 3: After the Mystery Box, the player sees a Green Star off a ledge. The player must stomp on a Brolder and take to the ledge and then throw the Brolder off the ledge.


Wii U version
Switch version

The player must be in Cat form in order to reach the Stamp, which requires climbing up the wall to the left after the Clear Pipe that goes through lava. The stamp is a Brolder.

Luigi sighting[edit]

The big tower that knocks down with the press of two P Panels has an 8-bit Luigi on it. The player must be in Cat form and climb to tower to see it.
