I thought that at first but dismissed it because it looked like it was flying better than I'd expect a penguin to fly, but watching it again, especially after the bounce when you get a better front view, that's definitely a penguin.

That must have been quite the rollercoaster of emotions for it.

Falls off cliff

"Ooooh, fuck fuck FUCK! This is going to hurt. I can see the water, too bad I can't swim over to it.

"Hey wait a second, I'm moving towards it more than I'm falling. Holy shit, I'M FLYING just like one of those other asshole birds that don't have to hop their way up and down these cliffs and then figure out where they parked their baby. This is AMAZING! I can just fly out past all the asshole sharks trying to eat us and surprise those asshole fish that try to get away from us and will never need to hop again! This is better than sliding on ice! Look at all those dumb fucks down there hopping like losers. Haha! I should buzz right by one of their heads!

"Wait, how do I control altitude in the air? It's not working like it does in the water. Fuck, I'm still falling, aren't I? Wait, those other asshole birds do this thing where they land on their feet. I just need to hop out of the air to--wait, no, it doesn't work like that, that's just how I get out of water. I need to put my feet under me. How the fuck do I do that? They won't go there! C'mon, landing gear deploy! Deploy! Aaah, abort mission! Flying was a mistake, this is going to hurt more than if I just took the fall! Brace for impact!

"OW! FUCK YOU ROCKS! Wait, what the fuck am I doing back in the air? My feet are above me now, that's even worse! Ok, let's stay on the ground this time! Brace for another impact! Aw fuck, my bracing bones are broken. I wish I was made of clay."
