Hello! I am new to the MerNetwork, but I found your thread on FinFolk's fabulous Mythic Tails! (I am eagerly awaiting my teal mythic tail--squeeeee)! Anyhoo, I just saw your post about underwater footage of it and I found this video clip of mermaid_bubu on Instagram of her swimming in the ocean (under water) in her mythic tail:

The fins move beautifully! Kind of wishing now that I got I got the extra fins!
