I love all the Papus but this one caught my attention by being So Angry! He's stomping his foot and yelling "I'm short but brave!" and if you interact with the Fadus sitting in front of this soldier he asks "Do you also hear the sound of a Papu talking?". This is my favourite interaction between NPCs in the game, the scene is adorable and the Papu's anger feels quite relatable.
As a fellow shortie I couldn't let the joke go unpunished >:(
