told Nox: "There's a special kind of drug here on earth called gillyweed that turns you aquatic with fins, gills and everything"
And, Hugorrr asked Nox: "If you've been to Earth, have you ever tried Gillyweed? It's basically a plant that makes you aquatic."
"Yep, I've heard of it, I got a chance to try it out a while back. It was pretty cool! Just like you guys said, it gave me gills, and it made a long fin on my back, with that fin even incorporating the spikes on me. It made my legs a bit weird, they could bend a lot more past the knee, and they each had flukes on the end. Maybe gillyweed isn't fully compatible with umbrakin? Couldn't really walk with those, but of course I just swam instead. It was a lot of fun!"
