'''Koopa Troopa Cave''', otherwise known as '''World 1-2''', is the second standard course of [[World 1 (Super Mario 3D World)|World 1]] in ''[[Super Mario 3D World]]'' and its [[Nintendo Switch]] port ''[[Super Mario 3D World + Bowser's Fury]]''. The course takes place in an underground cave with [[Koopa Troopa]]s, [[Goomba]]s, and [[Clear Pipe]]s, and it is unlocked by beating [[Super Bell Hill]], and its completion unlocks [[Chargin' Chuck Blockade]] and a [[Toad House]].

Koopa Troopa Cave additionally appears in the background in ''[[Super Mario Maker 2]]'', in the underground theme of the ''Super Mario 3D World'' style.

==Layout==
The course starts on a grassy hill with a Koopa Troopa and a [[Warp Pipe]] nearby, which leads to an underground cavern filled with Koopas and Goombas. Near the beginning of this cave is a [[Clear Pipe]] that leads to a section with a Koopa Troopa and a [[? Block]]. To the right is an area with some pipes and a hidden [[1-Up Mushroom]]. Following this is an area full of cloudy platforms; at the top is a straightaway, and a Clear Pipe that leads to an area with three openings. One contains a golden Warp Pipe that has three [[Gold Shell]]s; the other two contain Goombas. Past this section is a Warp Pipe that leads to an area full of Goombas, with a Star near the top, and a nearby Warp Pipe leading to the [[Goal Pole]].

==Collectibles==

===[[Green Star]]s===
*'''Green Star 1''': The first Green Star is floating among some cloud platforms.
*'''Green Star 2''': The player needs to climb three purple blocks to find a purple [[Mystery Box]]. Inside, they must defeat two Koopa Troopas to reveal the second Green Star.
*'''Green Star 3''': At the end of the level, the player finds a [[Goomba Tower]] with the final Green Star in the middle of the stack.

*Just after the Clear Pipe to the last room, there is a rectangular ? Block. The player must get on top of it and jump to reveal a hidden rectangular ? Block. Jumping on top of that block reveals another, allowing them to reach a ledge. The player can then enter the Clear Pipe on the wall to warp into an enclosure below the ledge, containing the Stamp and several Coin stacks. The stamp is a [[Coin]].

==[[List of Luigi sightings in Super Mario 3D World|Luigi sightings]]==
Right at the beginning, if the player turns the camera to the right, then an 8-bit Luigi can be seen on the wall, crouching and uncrouching. A second 8-bit Luigi can be seen at the beginning. If the player waits until the in-game timer says 104, a Luigi will exit the pipe, and go back in at 99 on the timer. A third 8-bit Luigi can be seen on the world map. A Luigi will eventually exit the pipe on the top of the icon.

==Secret Warp==
*[[Cat Mario]] is required. Slightly to the right of the clear pipe leading to the stamp, Cat Mario must climb the wall to reach the ledge with an orange Warp Pipe that leads to [[World 2 (Super Mario 3D World)|World 2]].
