World Crown: Mystery House Marathon

Presenting you with challenges faced in previous Mystery Houses, and with some original puzzles and remixes along the way, the World Crown Mystery House lives up to its name. Thirty Green Stars and a Stamp are at stake here. Fortunately, you don’t need to collect everything in one run. If you get to a room that is consistently stopping your progress, you can leave the Mystery House and try again later. Green Stars that you’ve already collected will be saved.

Green Star #1

Three Koopa Troopas are an easy start. Don’t get hit by their ricocheting Shells!

Green Star #2

It can be surprisingly easy to mess this room up. Make sure you jump between pendulum platforms when they are close enough that you can easily make the jumps. Don’t miss the Green Star in your first try, as you may not have time for a second chance.

Green Star #3

Use two Brolders on two of the P Switches; stand on the third one yourself.

Green Star #4

Grab a Fire Flower from the ? Block and light the four torches in the corners of the room.

Green Star #5

The room rotates the Green Star toward you—just avoid the Peepas until then.

Green Star #6

The crates in the upper-right corner of the room hide the Green Star.

Green Star #7

The Goomba and Mini Goombas that rush you in this room should be simple to deal with. If you stand in place and time your jump just right, you can take out all the Mini Goombas without moving an inch.

Green Star #8

You can either throw a baseball down to the star, or you can jump down there and get it yourself.

Green Star #9

Turn one of the Hop-Chops into a springboard, then ground pound off it to be launched high enough to grab the star.

Green Star #10

The Thwomps will reveal the terrain when they crash down. Use them to get to the star above your start point.

Green Star #11

Use a ice skate to slide past the Walleyes and reach the Green Star at the bottom of the hill. If you lose the skate, you’re not going to make it.

Green Star #12

Grab a Super Bell from the ? Block, then hit the P Switch behind the right wall to make the Green Star appear.

Green Star #13

You start at the bottom of a tower. Luckily, the previous room handed you a Super Bell! Scale the tower as quickly as you can; the star is at the highest point. Don’t leave the area right after collecting the star! You can pick up a spare Super Bell from a glowing spot on the ground near the Green Star’s location, and that might be useful to have.

Green Star #14

You need to use the Beep Blocks to get up to the wall, then use your Cat Power-Up to climb the wall and reach the star.

Green Star #15

This is possibly the hardest room in the marathon. Scale the falling sections of wall to reach the star at the very top. Don’t forget to rest on each platform for a brief moment (very, very brief) to reset your climb time.

Green Star #16

You can either use the rotating conveyor belt on the wall with the Cat Power-Up to reach this Star, or you can use a spin jump to make things easier.

Green Star #17

This Rabbit is very fast. Let the Dash Panels boost you at him—don’t try to jump! Just concentrate on running right into him to make the Green Star appear. Don’t forget to touch the Rabbit with the touch screen in order to catch it easier.

Green Star #18

Hitting this P Switch with a baseball can be very difficult. When using the Jump Panel, try to move closer to the target before making the throw.

Green Star #19

Run to the right to rotate the room around to reach the Green Star. You can easily reach the star right away by just climbing up the back wall with the Cat Power-Up.

Green Star #20

You can take out these Bullies faster by letting them run at your starting position near the lava, jumping over them, and attacking them from behind to shove them off the platform.

Green Star #21

The middle ? Block here creates additional blocks that you can use as stepping stones to reach the star. The Cat Power-Up’s ability to climb wallscan make this room go by quick.

Green Star #22

The winding walkway looks intimidating, but thanks to the Dash Panels you can jump over two separate gaps to reach the Green Star, so long as you remain perfectly centered on the first walkway. Watch out for the Cat Bullet Bills!

Green Star #23

Use the Piranha Creepers here as stepping stones leading up to the Green Star.

Green Star #24

Thwomps guard two of the panels you need to light up, while a bomb is needed to destroy the blocks protecting the third. Use baseballs on these panels to light them up as soon as they are exposed!

Green Star #25

Use one of the potted Piranha Plants to eat up the Fuzzies along the walls, then defeat the Piranha Plants, including the one you used. The star appears once all of the enemies are gone.

Green Star #26

Run along this wheel, favoring the right side, and bash your way through blocks and Piranha Plants until the Green Star rolls into view.

Green Star #27

In this room, the spotlight calls in Cat Bullet Bills that can destroy the blocks you need to use to get to the star. You can’t hesitate once the shooting starts.

Green Star #28

Run along the Donut Block bridges, but be ready to jump to avoid the rollers being tossed at you by Spikes, as well as to escape the falling Donut Blocks. The rollers cause the blocks to sink!

Green Star #29

Boom Boom has come out to play! Unfortunately for him, you need only land one good stomp to finish him off. Time keeps ticking as he goes through the motions of defeat, so stay near the star panel on the floor to grab the Green Star the moment it appears.

Stamp and Green Star #30

Almost as a celebration of your victory here, the Stamp and the 30th star requires only a simple, straight run through piles of Coins. Run as fast as you can; the 10 game second time limit still applies here! Don’t forget to jump to cross the final gap between you and the star.

Stamp

This Sprixie House can be entered as soon as you reach World Crown.
