Yeah the emote glitches are great! Personally, I love the item glitches. When they're too large. I think FlyingGrass had an issue with a giant sword on a pup and then of course the infamous giant hecking satellite antenna that roams FH ever once in a blue moon that I have yet to encounter.
Oml, Vortex. ouo
Most already said it, but the famous tongue glitch, the possession one...
Even the famous emots where your character purposely looks broken... Those are the best ouo
