On this ride, you're raised on a cable to the top of the tower and then released to gently parachute back to earth. Mostly a children's ride, Jumpin' Jellyfish is paradoxically off-limits to those who would most enjoy it because of its 40-inch minimum-height restriction. For adults, the attraction is a real snore. Oops, make that a real bore - the paltry 45 seconds duration of the ride is not long enough to fall asleep.
