This is an interesting one I think - here we have I think one of the stars from the Hedgy Action Movie of the year reprising his role when he senses another hog approaching - shield up! Spikes go up and the new Alpha hog strolls into view - notice the Alpha just punts the other hog around to get him out the way and never even bothers to raise his spikes. This is a boss hog and that's Alpha Diplomacy in action.

If you like snorty hedgehogs then this is the video for you.
So here we have a bit of a feud going on - the hedgy that you see getting ambushed drinking did the exact same thing to the other hog the minute before, so that annoyed hog walks around and comes up behind the drinking hog and does the same thing back. Bless em.
