ELI5: How are penguins so resistant to falling?

So I've seen a lot of videos of penguins falling from pretty high up to rocks and they just get up like nothing happened? While I'm happy they're not harmed, I'm also very confused. Can someone explain?

It comes down to force=mass x acceleration.
Penguins have a very low mass, penguins are made up of mostly lightweight insulating feathers. So when they do fall, they hit the ground with very little force.
