'''{{world|3|castlen2}}''' is the castle of [[World 3 (New Super Mario Bros. 2)|World 3]] in ''[[New Super Mario Bros. 2]]''. The most common obstacles that are featured in this water-themed castle are [[Grinder]]s. The boss of this level is [[Wendy O. Koopa]].

==Layout==
Mario begins on a platform which is being circled by a Grinder. This is followed by two [[? Block]]s, one of them with a [[Super Leaf]]. This is followed by more Grinders bouncing from their tracks. A [[Bone Goomba]] follows, along with a hallway of [[coin]]s above a Grinder's track. This is followed by a [[Dry Bones]] and a vertical section where Mario has to climb up a series of orange platforms while avoiding even more of the Grinders. At the top is a [[Warp Door|door]] leading to the following room, where the checkpoint can first be found. Another ? Block containing a Super Leaf can be found. The next section features many more Grinders, as well as Big Grinders on tracks along the path. There is a [[Mini Pipe]] above which leads to a hidden area with two ? blocks, one with a coin, while the other with a [[Super Star]]. Then [[Mini Mario (form)|Mini Mario]] must wall kick and touch the Grinders to defeat them and get extra points. Another Super Leaf can then be found. A Bone Goomba can be found, followed by more large Grinders in an area with platforms that move up and down. This is followed by the boss door.

===Boss Battle===
The boss here is Wendy O. Koopa, whose battle takes place on a long orange platform with water below and blue pipes on both sides. Her attacks are mainly water-based. She can cause the room to be filled with water in which state Mario cannot attack her using jump moves, but with fireballs. Blowing her whistle causes [[Cheep Cheep]]s to swim in the water from each pipe, or cause them to jump out of the water below when it is dry. To defeat her, Mario has to stomp on Wendy's head three times when it is dry, or use [[Fire Mario]] or [[Gold Mario]] to attack her at any time.

==[[Star Coin]]s==
*'''Star Coin 1''': The first Star Coin can be found enclosed by a Grinder that travels on a reverse L-shaped track. It is located in the vertical section on the left where Mario climbs up orange platforms. One way to obtain it is to activate a [[Hidden Block]] with a [[1-Up Mushroom]] below the Star Coin by hitting it from a small orange platform, then jumping up from there. Otherwise, Mario should wait till the Grinders are not obstructing him and then jumping to the Star Coin.
*'''Star Coin 2''': The second Star Coin can be found after the checkpoint right after the section with giant Grinders, being guarded by a single [[Dry Bones]] on a platform with Grinders coming from both sides the water.
*'''Star Coin 3''': At the boss door, the player must look for a hidden block on the right wall. They should climb up that block to reach a ledge leading to the Star Coin. Another way to get it is to use a [[Super Leaf]].
