Can penguins get concussions?
Any creature can, but they may be designed to suffer shocks without injury, too.
I suppose it not beyond the realm of impossible. Are you planning on becoming a veternarian? Because I seriously doubt this question is going to be on the final test.
I... think so? Not sure.
Why don't you try and see. Oh wait, you don't have a penguin.
Hmmm.......I suppose if they are playing hockey there is a chance.
