Please help me with this! i just cant figure it out...

Is this the one with two exit points? To get to one (sort of on the middle) you have to navigate a small tunnel with barrles, mines and water. To get to the other (Far right) you have to navigate a tricky overhang in the landscape, which curves left a bit, but the wind is blowing right?

If thats the one, good luck! I eventually went for the far right one, and gave myself a headache blowing into the mic :D You have to make your worm go straight up almost, to get past that overhanging bit.

thanks, mate. now...any guidence for unlockable blow #2?

For #3, land next to the mine, then quickly jump away, deploy your parachute, and blow. Then after all that stuff blows up, carefully navigate the passage, and you'll probably have to use the same jumping trick at the end, though it will be harder. Once you make it through that passage, it will at least be somewhat easier.

I think #2 involves a very quick blow to get your worm to go straight up.
