- Location: Second floor. The entrance to this course is located behind the staircase. It is a picture smaller than the rest along the wall of the main room, depicting mushrooms growing on a mountainside.
- Description: As the name suggests, Tall, Tall Mountain is a rather tall mountain with a secret slide, large waterfall, and cap-obsessed monkeys.
- Bob-omb Buddy: Start going up the mountain. On the platform just before the first monkey, look down. There he is, buddy!!
Tall, Tall Mountain is the twelfth course. Can be accessed after unlocking the second floor.
Star 1: Scale The Mountain
At the very top of the mountain. It may easier to climb up above the Monty Moles than to go the normal way because you skip the rolling log.
When climbing above the gophers, you should backflip as it is much easier. Carry on going up, then long jump past the water fall to the other side. After a little way you will see a purple "!" switch. Ignore this, and carry on to the narrow stone ledge, cross this and then go to the top of the mountain. You will see the star now.
Star 2: Mystery Of The Monkey Cage
Go to the very top again and catch the monkey. He will ask you to let him go. Agree to let him go, then follow him and he will open the cage for you. The star will end up far, far below on a platform by the bottom of the waterfall.
Star 3: Scary 'Shrooms, Red Coins
Get all 8 red coins.
- The first four are found on the mushrooms near the beginning. Jump carefully, as one wrong step means falling to your death.
- The other four are found around the corner, on the cliff face above the Monty Moles.
Once you have all eight, jump back down to the Monty Moles. The star is on the mushroom right off the mountain, so long-jump to reach it.
Star 4: Mysterious Mountainside
Close to the top of the mountain, there is a square portion of cliff that ripples if you brush by it. Jump in to get on the secret slide. When the track splits (it will be marked by arrows beforehand), keep right. You have to go fast enough to make it across the jumps, so don't slow down. If you get to the bottom, your reward is a star.
If you die here, whenever you go back in the painting, you will find yourself back here until you beat the level.
Alternatively, you can skip the slide altogether, and jump on the Fly Guy's head (he's by the big brown log), and helicopter into the alcove with the star in it (the slide exit.) Note that the only way to do this on the DS version is to use Luigi's invisibility power.
Star 5: Breathtaking View from (the) Bridge
Climb up the mountain all the way to where the waterfall starts. On the bridge right before that, you will be able to see a small hole behind the waterfall. The star is contained there, so jump into the hole and get your star.
This was moved to star 7 in Super Mario 64 DS.
Star 6: Blast To The Lonely Mushroom
Long jump from the mushroom where the red coin star is to the pathway far below. Go over to the cannon. Shoot to the mushroom with the star out on it. The Bob-omb Buddy is standing on a hard to find ledge. Take the hard way up the hill and just past the purple people thrower there is a wooden plank, after the plank you will be on a small island. Look down to your left to find a small gap that has Bob-omb Buddy. Jump down.
On the mushrooms with the red coins, there are three little mushrooms just past the yellow exclamation box. Stand on the middle one to warp to the beginning of the cannon path. Aim the cannon so the tip of the bottom aiming reticule is at the top of the cloud above the star.
Alternatively, you can jump on the fly guy and simply helicopter to the lonely mushroom with the Star on it.
Star 6: 5 Secrets of the Mountain (Nintendo DS)
As Mario, climb to the top of the mountain and get the Wing Cap. There are five rings of coins with one coin in the center. The coin in the center is the one you are aiming for. You will need to take a couple landings. After collecting the five coins, the Star will appear at the top of the mountain.
Star 7: 100 Coins
This is a snap. Get all the coins in the slide (there are three blue ones), then just search around for the rest. After dropping out from the slide, jump over the fence and you'll land about where one normally starts. Now you can roam for the rest of the coins. Doing it the other way 'round won't work, because you won't be able to jump up and get the star while in the slide.
