First time getting stung! Wow, color me green, I'm jealous at your luck!
Swimming though those nettles, i just kept remembering a horror movie I watched a long time ago. I can't remember it's name, but it was in a research facility at the bottom of the ocean and at one point, something caused jellyfish to swarm the facility and clog all the vents and everything and start killing people. As you said, gotta check to make sure buddy hasn't been eaten!
Sphere? We had the same conversation last weekend
