Location: Upper floor of castle, 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!!
Star 1: Scale The Mountain
At the very top of the mountain. I think it is easier to climb up above the gophers than to go the normal way (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. There are 4 on the mushrooms, and 4 on the cliff platforms (above the gophers).
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.
- Note: 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 this will not work on the DS, in the DS version they added a grating to the wall to prevent this.
Star 5: Breathtaking View From The Bridge
Scale the mountain until you reach the top just before the bridge where the monkey's cage was. There is a purple question mark button before the bridge that once stepped on makes a box appear in front of the star inside the waterfall. Run to where the cage was before and jump onto the box before the time runs out. Once inside the waterfall you may retrieve the star.
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 where the wooden plank is past the purple thing that chucks you, there is a gap between the two ledge parts, jump in between them and you will find the Bob-omb Buddy. On the mushrooms where the red coins are, if you walk past most of them and get to the second last mushroom with the coin is, jump onto it. Go to the next one and that and make a U-Turn type thing (big, small, big mushroom)if you jump to the one that is in front of him(a small one with 3 dots on him). jump onto the first white dot or the center of the white dots and it will take you to a secret place and follow the narrow track down to the cannon. If you shoot just above the star where the cloud is, you will get the star.
Alternatively, you can jump on the fly guy and simply helicopter to the lonely mushroom with the Star on it.
You can also long jump onto the mushroom where the red coin star appeared and then long jump down to the narrow path.
Star 7: 100 Coins
This is a snap. Get all the coins in the slide (there are three blue ones,only if you have the old version), 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 (I think), because you won't be able to jump up and get the star while in the slide.
