The attraction's name comes from the jellyfish-themed parachute ride vehicles, the bubble and 50-foot (15 m), kelp-themed towers. Jumpin' Jellyfish has a sister-themed attraction that opened in September 2001 at Tokyo DisneySea. This attraction is similar to that of the former Maliboomer, but scaled down to more child-sized proportions and rethemed. The 180-foot-tall (55 m) Maliboomer required riders to be at least 52 inches (1,300 mm) tall, whereas Jumpin' Jellyfish only requires riders to be at least 40 inches (1,000 mm).
