Hey hey.Can anyone help me on Snowman's Land,Course 11. Look I completed..

The pink bomb is in the igloo. Get across the Snowman's head (I'll tell you how in a minute) and drop down onto the small cliff. Crawl into the igloo. The Bob-Omb Buddy is in the back.
To get across the snowman's head, you need to use the Big Penguin. You can jump on top of it (which I find very hard to do), or you can just walk beside it. Remember, the Penguin doesn't just go forward, he also backtracks sometimes.

Also, in response to your request, I am working on a walkthrough for the entire game, but it will take some time to complete.

It depends on which Star you're going for...
To get across the Big Snowman's head for the first Star: Snowman's Big Head, all you need to do is follow along with the Big Penguin so that you don't get blown away!!!
To find the Pink Bomb, you'll need to get into that Igloo by the Frozen Pond and to get to the Igloo you'll need that Shell on the other side of the Frozen Pond...
Keep Trying!!!

Snowman's big head: Start by going around the right side, you're trying to get behind this large mountain. Here you will find some enemies and quite a bit of water, avoid the water though as it is very cold and you will take damage whether you are underwater or just treading water. Notice the stretch of land with those sliding snow triangle things. Jump over them as you make your way toward where they are coming from. Double jump here to get up to the walkway and begin climbing. You'll come to an ice bridge with a large penguin. The snowman's head will try to blow you off the edge, you need to use the penguin for cover from his icy breath. The penguin follows this basic pattern. Walk, stop, run, stop, walk backward, stop, repeat. Stay behind him and you'll be able to make it to the other side no problem. If you get blown off Mario will lose his hat (just go pick it up) and have to climb all the way up again. Once you get past the bridge, stand on the highest part of the path you can and double jump to grab the edge of the snowman's head. Walk slowly around to the front of the forehead and you'll find the star.

Chill with the bully: To the right of where you start, you will notice there is a big bully on the
Icy platform. Jump onto it and prepare for battle. The ground is slippery
Which makes it more dangerous, just keep jumping in the air and pressing B to
Kick, that's the easiest way to defeat him. All you have to do is knock him
Off the edge and a star will appear.

In the deep freeze: On your left side when you start, notice there is an ice structure with a star inside it. It's not going to be as easy to get that star as you might think... Or perhaps it will. What you want to do is enter from any direction and notice there is one point in the middle basically where all the entrances meet that you can jump into the air. You need to face the back wall of the
Level, in the direction opposite the direction you face when you start, facing away from the mountain area. Double jump and you should be able to get hold of a ledge. From here you can get on top of the structure and drop down onto the star. It is possible to triple jump from the ground and get on top from the side, but to be honest, it's more difficult than doing it the correct way, especially once you know what to do.

Whirl from the freezing pond: Get around behind the mountain once again, to the area with the water which you can swim in, but damages you to do so. Stand at the bottom where the triangle shaped moving snow slides stop, and face the direction they come from, now turn 90 degees to your right and notice the ledge up above which you cannot reach. What you have to do is jump in the air and land on one of those flower enemies in the water, that will bounce you high in the air and allow you to glide onto this ledge. Here you will find a shell in one box, and a star in the other box.

Shell shreddin' for red coins: The first red coin is found by going immediately right and staying along the side of the wall. In the corner of the level over here on the other side of the tree you will find the first red coin. Now stay along the wall to reach the other corner, just on your left you should see the second red coin here. Now go to the area with the water which you can swim in, but damages you to do so. Stand at the bottom where the triangle shaped moving snow slides stop, and face the direction they come from, now turn 90 degees to your right and notice the ledge up above which you cannot reach. What you have to do is jump in the air and land on one of those flower enemies in the water, that will bounce you high in the air and allow you to glide onto this ledge. Get the yellow box with the shell inside and don't jump back down, along the side here
There is a red coin and it leads in in the direction of not one, not two, but three more red coins, you should be up to six at this point. Jump down and make your way back to the area where the big bully is. The final two red coins are located on that super cold damage ground below the bully, you need the shell to get them without taking damage. Once the star appears go back to
The start and get it.

Into the igloo: Get around behind the mountain once again, to the area with the water which you can swim in, but damages you to do so. Stand at the bottom where the triangle shaped moving snow slides stop, and face the direction they come from, now turn 90 degees to your right and notice the ledge up above which you cannot reach. What you have to do is jump in the air and land on one of those flower enemies in the water, that will bounce you high in the air and allow
You to glide onto this ledge. Grab the yellow box on the right to get the shell from it and turn around. Drop down and note that beside the place where those snow slides are coming from, there is a steep ramp with a line of coins on it. Go up this ramp using your shell to find the igloo at the top. It's small so you have to crawl inside (hold Z and use analog stick to crawl). Go
Forward until you hit a wall, make an immediate right then an immediate left, GO foward until you hit a wall and go around the corner, you should pass a blue box on the other side of the wall right about now. When you turn left (and possibly encounter a flower enemy) note that the blue box area is still on your left and blocked off. Not so! Double jump and you can grab the top of the ice ledge. Now drop down and get the vanish cap, use it to go through the ice, return to the start, and get the star! You can also go talk to the little bomb guy if you want.

Hope that helped oh and don't forget the hundred coins

Hundred coins: On your left when you start there is a line of three coins, the third one turns into an enemy which drops five coins when killed. Eliminate the three flowers as well to bring your total up to 16/100. Make your way to the opposite corner with the single red coin and flower enemy, there's also another flower enemy around here and one of those flying red things. In the next corner there is another red coin, two more flower things and another fake coin enemy, bringing you up to about 39/100. Kill two or three of the flowers in the next area but leave one to bounce off of to reach the shell. Use the shell to get the four red coins up here, the two red coins below the bully and all of the coins up to the igloo in the water part. Don't go into the igloo yet, get off your shell and begin climbing the mountain. There are a few coins on the way up, all the way until you reach the other side of the penguin bridge. While standing on the other side of the bridge you can look straight down and see the igloo, drop down to it from here an crawl inside. At this point you should have approximately 70/100. Kill the two flowers and two Goombas right inside the igloo then make your way to the vanish cap again, killing the third flower on the way. Your destination once you have it is of course the super coin room. If you followed all this, this will bring you
Over 100, if not, you probably skipped the mountain.
