Last night while I was completing one of Tiny Tina's side missions in the Tundra Express I saw that the bandit house on the path from the entrance had a snowman's head (complete with carrot nose, and I think a top hat) sitting on the ground next to the house's door.
At the time I thought it was odd that I hadn't noticed it before but just chalked it up to not paying attention. But today, after going back to the area I see that it isn't there.
Does anyone know why it showed up? Does it have any meaning?
