I actually was running on the beach and slipped on a dead one once when I was a child.
That sounds like it was quite humorous...like slipping on a banana peel. Did you feel cartoonish? Should I carry a bag of dead jellyfish around just in case someone ends up chasing me down the street?
hahhah like Mario Kart! Definitely not something a lot of people can say they've done. Seriously though they are extremely slippery.
