SpongeBob was here
If you understand this title, then you, sir or madam, are a person of culture. There’s an episode where SpongeBob and Squidward ride a boulder across the seafloor to deliver a pizza. However, this real-life phenomenon is a lot more mysterious and, if we’re being honest, quite freaky to think of.
Scientists have recorded boulders seemingly moving on their own accord for years now, but nobody has offered any theories as to why this is. You can see how far this boulder has traveled, and without footprints or tracks of any sort, we can assume nobody’s hand played a role in moving the rock.
