Runo was finally starting to figure out how to balance on his new legs. It was still a bit shaky, but he was upright for now, so that was something. At least until Tanikazi's yelling startled him into losing his balance. Letting out a squeak, he fell against the tank's glass, arms flailing for something to grab on to. Ending up mostly on the floor again, he looked up over at the yelling creature again with a slightly upset look. He didn't understand why the furry-eared one was so angry about seeing them or what a "robot-floaty thing" was. And a taser? That wasn't something he was familiar with either, but it sounded like maybe it hurt a lot. 

Leaning on the tank, the recently bipedal merman pushed the slightly long hair out of his face and attempted to stand up again. Legs were tricky...was he really going to have to run with them already? Sighing, he took a few shaky step forward, almost falling again at several points. As he grabbed on to the doorframe on the way out, he felt a little bad about wanting to leave the tank; he knew that he was expected to keep up, but how could he do that with new appendages that he'd never used before? It was way better than being stuck like before, but he was probably going to slow them down like this. Maybe he could stick to the walls, at least.
