First upload everyone!
 
So anyways, I might as well go ahead and explain what the hell you are all looking for (and why it have “equestria at war mod” as a tag).
 
Story time!
 
So, a while ago me and a friend were voice chatting at Discord about Equestria at War (we both really like it), and then, we started talking about the most underrated nation in our opinion:  
Pengland, the only place in the world of the mod that contains penguins.
 
Blah blah blah, we realized how great penguin marines since they literally are born to swim as griffons are born to fly.
 
THEN we realized that Hippogriffs also would have great marines, seaponies and all.
 
And in the end I said:  
“A penguin-hippogriff hybrid would be the ultimate marine then!” As a joke.
 
The joke went too far and I went ahead with the idea, two times even, this is just the superior second product that I felt was worthy of being uploaded here.
 
Thank you for coming to my TED talk.
