Swing from rope to rope 10 times in a row.
This achievement requires that you swing from multiple ropes a total of 10 times in a row without falling off. This can easily be obtained on USA Level 3, Jungle Gym Hijinx. Very near the beginning of the level, you will come to two ropes that are close to one another. Jump up onto the first one and then keep jumping back and forth between the two a total of 10 times to unlock this achievement. Feel free to go as slow as you want.
