Bowser's Castle (or World 8-) is the sixth and final level, as well as castle of Koopa Planet from Newer Super Mario Bros. Wii. This castle is a trick castle where the title suggests that Bowser is fought at the end, while there is no boss much like the castles in the lettered worlds. The door at the end leads to a large area with Peach captured, but hitting the switch will drop you to an underground cavern, signaling the start of Koopa Core.
- Star Coin 1: After the first series of swinging platforms, take the bottom path and avoid the Podoboos in the way of the Star Coin and collect it.
- Star Coin 2: Near the area with the Sledge Bro, take the path below it and you will find a red pipe. Enter it to enter an area with a fast swinging platform, and jump off it to collect the second Star Coin.
- Star Coin 3: Before the door, there is a double Fire Bar. The Star Coin is visible in this area; you will need to avoid the Fire Bar to collect it safely.
