I defeated the crab inside of the Airyglyph Aquaducts... I read the official guide book for this game to see the answer, and you know what it said? All it said was that after you battle the crab, you will be able to get out of the aquaducts onto the main road of Airyglyph. Bullshitzu. I tried for 6 feakin' hours with my dad to find any possible way out, and we simply couldn't. We found a ladder, around the side of some ledge outside the room of the crab battle, but it lead us to a dead end, and we keep falling through the ice in the room where the crab was. We tried battling the globby thing in that small room within our vicinity, and nother happened, and we even tried to climb back up the slope to the top. We couldn't get past 3/4 of the highest slope.
