Once the thing started thrashing it was hard enough just hanging ON, and Robin was just lucky he was caught. "Nice timing! Now we can---!!"
*WHAM!!*
Beetle must have absorbed most of that impact, Robin realized shakily, and his second coherent thought was that this fall was taking a lot longer than it should've. Were they flying...?
No, he decided, about six seconds after they hit the cobblestones. He tumbled by reflex and spent at least another ten enjoying the solid ground.
"... uhhh. Beetle?"
There was a rhythm, something to focus on. It was around the time the world stopped spinning that he recognized music, the kinda music got played by hired suits at fancy parties. The sound was so out of place, he almost didn't register the hordes of crow-people performing a ballet in perfect unison.
"Okayyyy, now entering Arkham Dance Hall."
The mass continued in eerie, sweeping grace as Robin reeled to his feet, right up until the movement of the nearest crow took it too close and it tried to decapitate him with a short sword.
He ducked just in time to shave a few spiked ends. "Heyy!!" He slid around it but it wasn't even looking at him anymore, moving along with the dance as if nothing had happened. "I liked that haircut," he protested, and in keeping an eye on the first one was distracted from the next three.
