The secret star is in the first level in freezeflame galaxy so click on the first star and now i'll walk you through it. When you first arrive you have to race that penuig then go after him ( HINT: if you spin while walking on ice you'll be able to skate ), then go on the sling star to the summit. Now get the big mystry coin and get the ice flower ( if you want to go to the big mystry coin in the water and a ton of coins will appear, and if you want to collect them ). Then go to where you see these other things sprinkleing water ( there may be a 1-up there ) and backflip ( crouch then press A ) you will see another sling star fly in it. You should appear on another part of the summit the will be a fire flower there, now you must use it to burn down the snowmen, but there are also frozen bats the only way you can kill them is if you shoot a fireball at them. then get past those things that come in and out and get there in time to melt the other snowman once you completly burn it another sling star will come up. The next part you have to do it again melt the snowman to get across to the other side, get past those " things " without getting pushed and get the other fire flower, but there are boulders if you get hit once you will die. Get past them burn the snowman get on the sling star and now try not to fall off or you'll also die. The last part is when you have to wall jump ( hit A on a wall ) without getting pushed by those " things " when you FINALLY reach the top the star will be there.
