Bleep! An Axolotl Fart? (Patreon)

I keep forgetting to share this 39-second funny outtake from the Halloween episode. 

It was late. I was in a spooky mood and we were talking about the next bit to record when there was the most adorable 'bleep' sound from behind me. I had no idea what it was. 

What was it? You be the judge.
