Bowser Jr. Boss Battle is an attraction you can experience after collecting three keys in theSUPER NINTENDO WORLDKey Challenges.
We’ll explain how to play the Boss Battle, strategies for clearing it, and tips for getting a high score of 55 points or more to earn the stamp.
The inside of the fortress before the battle is also designed to be fun to explore.
Take your time looking around the fortress too—you may even get a glimpse into Bowser Jr.’s personality, not just the battle itself.
What is the Bowser Jr. Boss Battle?

Bowser Jr. has stolen the Golden Mushroom from the Mushroom Kingdom!
Collect the keys in SUPER NINTENDO WORLD and you can unlock the entrance to his hideout and go inside.
Use your whole body to take down Bowser Jr.!!
It’s an experience where both adults and kids can really let loose and play!!
* To experience it, aPower-Up Band is required. Companions of guests who have a band can watch the Boss Battle from behind.
How to Enter the Fortress (Hideout)

Hold your Power-Up Band up to the keyhole at the entrance, and the light will change from orange to green.

If you have successfully collected three keys, you can go inside.
Even if you have attempted the Key Challenges, you cannot enter if you failed the games or, unfortunately, a communication error prevented a key from being recorded.
If you are unsure, check the smartphone app or the nearby monitor to see how many keys you have collected.
Inside the Fortress

Bowser Jr.’s emblem is drawn on the floor at the entrance.

There is a statue of Bowser Jr. farther inside.
He is holding a paintbrush.

There was Goomba graffiti drawn on the wall.

Mario has an X drawn over him.
From Bowser Jr.’s point of view, Mario is the enemy, after all.

A painting showed Bowser Jr. holding the winner’s trophy.
Koopa Troopa in second place and Shy Guy in third are celebrating too.

Farther inside, Bowser Jr.’s flying vehicle, mushrooms, and other items are piled together.
It looks like a child’s toy box.
You can also hit the glowing block on the left.

There is also a treasure chest.
Touch the keyhole and it lights up in colorful colors.
How to Fight the Boss Battle

A video shows the Golden Mushroom when it was kept at Peach’s Castle.

Guests form groups of about ten and wait on the numbered spots on the floor just before the Boss Battle stage.
A video then explains how to play the Boss Battle.
After the explanation, it is finally time to head to the battle stage.

Look for the large footprints and go to the number the crew member assigned you earlier.
If you do not have a Power-Up Band, cheer from the gap behind the pillars!
(You cannot move closer to the front, because doing so would prevent you and other guests from playing.)

In the Final Battle, your silhouette appears on the large screen in front of you.
The character on screen moves as you move your body, so fight by jumping and crouching!

Once you get a Fire Flower, you can throw fireballs from your hands.
Aim for Bowser Jr. and throw them!!
How to Get a High Score: Video
Victory

If you defeat Bowser Jr., a thank-you letter from Princess Peach appears at the exit.
* I have never encountered a defeat, so I do not know whether losing is possible.
How to Get a High Score!!
You can earn a stamp by collecting 55 coins or more, so start by aiming for 55.
How to Knock Bob-ombs Away
At the beginning and again later in the battle, swat Bob-ombs toward Bowser Jr.
What Should You Aim For?
Do not swat Bob-ombs randomly—aim them so they hit Bowser Jr.
Simply swatting them does not earn coins, so keep that in mind.
How to Swat Bob-ombs
Sometimes they will not fly well if you hit them with your palm.
For easier control, use the part of your arm between your wrist and elbow to send them flying.
Because this keeps them close to your body, you have more time to let a Bob-omb come in, aim calmly, and then swat it.
Crouch When a Cannon Appears
A cannon suddenly appears from the ground very close to your character two or three times.
Bullet Bills shoot out of the cannon, so crouch quickly when one appears.
Bullet Bills can also fly in from farther away, so crouch to avoid them.
When You Can Shoot Fireballs
After picking up a Fire Flower, you will be able to shoot fireballs.
How to Shoot Fireballs
Relax your shoulders and move quickly from the elbow through the palm, using a snapping motion of the wrist.
If your movement is too small, the fireball will not leave your hand.
You need a certain amount of movement.
But if the motion is too large, you cannot fire many shots, so move your arm only as much as you can while keeping the motion quick.
What Should You Aim At?
Aim for Bowser Jr., Koopa Paratroopas (winged turtle enemies), and Piranha Plants.
Watch Out for Piranha Plant Flames
With a whooshing sound, flames burst out from the Piranha Plants.
Just like with Bullet Bills, crouch to dodge them.
If you get hit, the amount of time you can attack becomes shorter.
Summary
With a Power-Up Band, you can enjoy this after successfully completing three Key Challenges.
It’s a new kind of game that gets your whole body moving.
