From the creators of the internet sensation Grumpy Cat, we happily present to you... the one and only...
Grumpy Bear! (see left creature in the picture below)
On a serious note, I can't believe that I never noticed this before. Having watched Triple Threat (the episode of this still) a bunch of times now, I don't get how I missed this. When I saw this, I was gasping for air while I pulled out my screenshot taker, telling myself "Oh, god, he has the lip and everything".
Gotta love Viqtarr's facial expressions.
