Info from Licensor: "Me and my mates (4 of us) decided to go on the parachute boat. Two went first and the got dunked in the water and Julz (who was with me) where thinking cool that looked fun. Our mates came off and said nothing and when myself and Julz ascended we looked at each other and saw that there were a lot of jellyfish below us.
