Super Mario 3D World: Crown-Mystery House -- Mystery House Marathon

The last Mystery House is a long one. You have to collect 30 Green Stars and have ten seconds to make each one appear and collect it. Once you collect the Green Star, the timer stops, so you can take a break if you need to. If you fail to collect one, you'll have to start over. If you find this to be a bit difficult, having more players can make things a little easier.

1. Kill three Koopas to get the first Green Star.
2. Run and jump on the pendulums, then jump for the Green Star. Avoid the spike bar on the last pendulum. If you fall off the last pendulum, you may be able to hop back on and get the Green Star.
3. There are two Brolders and three P-Switches. If you are playing solo, throw the Brolders onto the P-Switches and stand on the last one. If you are playing with others, have them stand on the switches.
4. There's a triple item block on the back wall. It contains a Fire Flower. Light all four torches to make the Green Star appear. You'll have to jump to light the torch in the back left corner.
5. You'll be in a spinning room with Peepas. Throw fireballs to make the Peepas temporarily transparent. Get the Green Star when it's close, on the left side.
6. You're in a room full of crates. The Green Star is in the set of crates in the back right corner. The crate it is in is the lower left corner.
7. There are six Microgoombas and a Goomba in the room. Defeat them all.
8. Throw a baseball down the slope at the Green Star (or hit one down with a fireball, or slide down). Avoid having the baseball hit a Biddybud or it will miss the Green Star.
9. There are four spring enemies, one of which turns into a spring. This one is on the far right. Turn it into a spring, then quickly ground pound it to reach the high platform with the Green Star.
10. There are two Thwomps and a footlight path so you won't fall. Stand on the Thwomp, then wait for it to rise so you can run to the Green Star.
11. This one can be a little tricky. Jump to land in a Kuribo's Ice Skate and start sliding down. Follow the coin trail and avoid the Walleyes. Repeatedly hit (Y) for a speed boost. Try to line up with the Green Star at the end so you slide into the warp box.
12. Grab a Super Bell from the back wall, climb up over the right wall, hit the P-Switch, climb back up the wall and jump over the left wall to get the Green Star. You can split the work with two or more people.
13. Climb up the tower, avoiding the moving brick blocks. The Green Star is at the very top. Before you warp, you may want to hit the glowing spot nearby for another Super Bell.
14. There are Beat Blocks moving at double time forming stairs up to a wall. Try to reach the top Beat Block, then climb up the wall. The glowing spot here also has a Super Bell.
15. Climb up the wall, which will fall away after you clear a chunk of it. Run quickly and grab the Green Star on the rock.
16. There are Fuzzies circling a wheel on the back wall. The Green Star is surrounded on three sides, forming a "U". You can run up the wheel, or spin jump to the Green Star, which is easier.
17. Use the boost pads to chase the bunny. Catch it for the Green Star, then grab the Green Star.
18. Grab a baseball, run and jump from the springboard, then throw the baseball at the P-Switch. The baseball may grab the Green Star for you.
19. You're in a spinning cylinder with Piranha Plants. Run to make the cylinder spin so you can reach the Green Star. Alternatively, if you have the Cat Suit, run up the wall and jump for it.
20. Push two Bullies into the lava. It's a little easier with a Cat Suit.
21. There are giant item blocks that form bridges when you ground pound them. Jump from the top bridge to get the Green Star. Alternatively, with the Cat Suit, run up the wall.
22. There are boost pads at the start of a narrow path. Line yourself up with the center, run and jump across the platforms to get the Green Star. Alternatively, you can run around on the platforms. Avoid the Cat Bullet Bills.
23. There are sleeping Piranha Creepers forming stairs to the Green Star. You have to hit the one at the top to reach it. Bounce on all of the Piranha Creepers or climb the wall with a Cat Suit and bounce on some of them.
24. There are baseballs, two Thwomps, and a bomb. Use the bomb to clear out the lower gray bricks, then use the Game Pad to clear the ! Switches. You can also throw baseballs at the ! Switches.
25. Grab a Potted Piranha Plant and have it eat the Fuzzies. Then stomp both Potted Piranha Plants for the Green Star.
26. Run over the cylinder with the Piranha Plants. The Green Star is on the right side, the side closest to the screen.
27. There's a large spotlight over some gray bricks. Wall jump up between the bricks, then jump for the Green Star. Cat Bullet Bills will appear if you enter the spotlight.
28. There are two Spikes throwing spike bars onto donut lifts. Run, dodge, and weave to make it to solid ground with the Green Star.
29. Boom Boom is here. Hit him once to make the Green Star appear.
30. There are stacks of coins on the path ahead. Coins will rain down. Run to the edge of the path, grab the stamp on the way, and jump off the cloud to reach the Green Star where the Sprixies are gathered. You're done!

The stamp is of a Starman.

Thanks to Ashwin, Derek, John, and Tony for helping me complete this level.

Super Mario 3D World: Bowser- Mystery House -- Mystery House Claw Climb

There are 10 Green Stars in this level. Grab a Super Bell and start climbing.

Climb up the wall for the first Green Star. There are Super Bells here. In the second area, the Green Star is above you. Run under the low ledge, climb up the wall, and run to the left. In the third area, quickly climb up the beep block wall. In the fourth area, run across the lava using the bridge, then run up the back wall. The fifth area is the same as the first, but the Green Star is at the top. The sixth area is the same as the second, with bricks to break. The seventh is the same as the third, but the beep blocks are split into groups of two instead of four. The eighth is the same as the fourth, but the Green Star is on the back wall, over the lava. The ninth area is the same as the sixth, but with POW Blocks in the bricks. The tenth area involves running up a tall stack of blocks. The blocks will separate and fall away. The Green Star is at the top.

Super Mario 3D World: 6- Mystery House -- Mystery House Throwdown

Instead of battling enemies as the title suggests, you'll be throwing baseballs around to collect the Green Stars. For the first Green Star, pick up a baseball and throw it down the slope, in the center, aiming for the Green Star. Alternatively, you can jump down there and jump back up after you grab it, but this is not recommended. The second Green Star is on a flip-switch. Pick up a baseball and jump so that it appears when you jump to throw the baseball. For the third Green Star, use the springboard so you can aim the baseball at the P-Switch. In the fourth area, jump and throw the baseball at the POW Block. This will get rid of the Biddybuds for a 1-up and make the fourth Green Star appear. In the fifth area, throw the baseballs at the ! Switches behind the Thwomps. Clear them all to make the fifth Green Star appear.

Super Mario 3D World: 4-Mystery House -- Mystery House Mad Dash

There are ten Green Stars in this Mystery House. Instead of beating a series of enemies, you'll have to run to reach the Green Stars before time runs out. You have ten seconds for each stage.

The first stage involves running and jumping on the springboards to reach the Green Star. Stage 2 has wavy hills and ants with spiked caps. Stage 3 has you running away from a Banzai Bill with crates in your way. Stage 4 has Spikes throwing spike bars at you. Stage 5 has a narrow path with coins. You can jump across the gaps, and after you get the Green Star, get some coins from the brick block.

Stage 6 has boost pads and Thwomps. Stage 7 has pendulums you must jump to. If you fall, you can get back on the pendulum without backtracking. Stage 8 has several Goombas and Microgoombas. Ignore them and blow them away and keep going. Stage 9 has Cat Banzai Bills and a narrow path. Stage 10 has Spikes throwing spike bars on donut lifts, which makes them disappear. Keep switching sets of donut lifts to make it across. They will reappear after a short while.

Mystery Houses are places where you can earn many Green Stars. In this one, you complete challenges in a short period of time to get a Green Star, then warp to the next challenge. Any Green Star you collect, you can keep, but you must collect one after defeating an enemy in order to move on.

In the first room, you must defeat two Galoombas. In the second, two Koopas, in the third, two Cat Goombas. You'll get a Super Bell from one of the Cat Goombas. The fourth room has four Conkdor. Use the Super Bell to defeat them more easily. The fifth and final room has two Fire Bros. After clearing all five room, the Green Stars will be added to your total.
