What I saw was a mass of tentacles large and numerous enough to envelope my WinderWave. They swayed in an odd, hypnotic pattern and half of my crew was enthralled. As we got closer I thought I saw what was at the center of the mass... for the life of me I can't rightly describe it, it was if I were seeing sound and hearing sight.
The only thing that saved me was my love for my kids and crew. I snapped out of the calm madness and pulled the Orca far away from that creature.
The Myriapodia insist the tympanic medusa are harmless, that's not something I'll wager on.

The term I would use for TympanicMedusa is "Useful". Many useful things are harmless when appropriately addressed, and harmful otherwise. If you want harmless, send your messages by CarrierFish? instead. Hope you brought a big tank full!
