I wonder if we will get to see the Tetrapteron in the new movie since the new movie is supposed to largely take place in or around water. The Tetrapteron is found in wetlands or near the ocean and hunts in flocks, so this would be really cool to see.
I just imagine a scene where the camera is panning over a body of water and there is just a huge flock of Tetrapterons that are a multitude of beautiful, bright colors, standing in the water or flying low over it like flamingos do.
Low flying Tetrapterons over turquoise water with the beauty of the rest of Pandora in the background. That just sounds so perfect 💙
