A single tumbleweed crossing your path is already a telltale sign that something is about to go down. So what about when hundreds of tumbleweeds getting blown every which way right in front of you? Yeah, that’s when you know the world is about to end. There’s no other acceptable explanation.
It looks like the entire horde of tumbleweeds grew sentient and decided to escape all at once. The apocalypse hasn’t hit yet but it’s most definitely starting like this, right? First, the tumbleweeds. Then the zombies.
