Bowser's Castle Strategy Party
The recommended party is Mario, Bowser and Peach. In Bowser's Castle, some enemies will flee when they see Bowser. If you don't want to fight much, include Bowser in your party.
How to Get to Bowser's Castle
Accessible via Lakitu Bus from Nimbus Land
After reporting about the battle in Barrel Volcano and the remaining Star Piece, you will be able to use the Lakitu Bus. Exit the palace, go left, and talk to the Lakitu Bus manager. This will allow you to go to Bowser's Castle.
Bowser's Castle Walkthrough Chart
Proceed Straight Through the Castle
Once inside the castle, follow the path straight ahead. There's a Chikuwa Bridge along the way, so be careful not to fall off.
Enemies May Flee if Bowser is Present
If Bowser is in the battle, Koopa Troopas and Goombas may flee. This is useful if you want to minimize battles, but it will also make it harder to level up, so if you want to earn experience points, remove Bowser from the party.
Proceed Through the Darkness
Follow the path and you'll reach a dark area where only Mario's surroundings are visible. Enemies will appear suddenly, so proceed slowly if you want to avoid battles.
There's a Save Point and Croco's Shop
After exiting the dark area, there is a save block and Croco's shop. There will be 6 doors and consecutive boss battles after this, so be sure to save.
Hidden Room in the Bottom Left
You can access a hidden room from the bottom-left corner of this room. Inside, there's an instant-use full recovery Mushroom and 150 coins, so be sure to collect them.
Conquer the 6 Doors
The 6 doors each lead to an action course, battle course, or puzzle course. Clearing 4 doors allows you to proceed to the next area. The course behind each door is random and unknown until you enter.
Area Features
| Action Course | - Easy if you're confident with Mario's controls - Excellent weapon for crossing magma |
|---|---|
| Battle Course | - 12 consecutive battles - Easy if your party is strong enough - Both rooms have excellent weapons |
| Puzzle Course | - Easiest if you look at the answers - Rewards are mediocre |
Avoid Difficult Doors by Giving Up
Once you enter a door, you cannot exit, but if the content is difficult, you can give up by pressing the - button. Giving up will return you to the front of the door, so if you open a door you find difficult, give up.
Different Items are Awarded
The items you receive differ depending on the course. Be sure to obtain the strongest pre-clear weapons: Drill Claw, Sonic Cymbal, and Star Gun.
