Beachgoers were advised to stay out of the water when a large creature was seen "swimming" of the coast.
Several people began recording the incident, including a YouTube user known as Spookums Migookums earlier this week.
Beachgoers observed the creature swimming close to the shore before returning to deeper waters. Many postulated it might be a 20-foot eel or snake.
The truth was eventually revealed when the Myrtle Beach Fire Rescue intervened, and they shared photos of the "electric eel" on their Facebook page.
What appeared to be an eel from far away, was nothing more than a log floating in the ocean.
Myrtle Beach Police Corporal Thomas Vest thanked the crew for a job well done, and the Fire-Rescue Department said on Facebook:
"Big shout out to Public Works and especially Tod O’Briant for assisting with the removal on his Labor Day holiday!"
Volunteers were able to pull the log onto the shore where they cut it up into smaller pieces and disposed of it accordingly.
Just a few days ago, another recording went viral when a group of people on vacation in Scotland claimed to have seen the Loch Ness monster.
"It was actually amazing whatever it was; it was big! This was in June so the beach was quiet at the time and no boats were out. I just really couldn't believe my eyes."
An alleged sighting was also captured in June when a grandmother and her grandchild claimed to have seen the Loch Ness monster. The footage of both incidents can be seen here.
In Siberia, a "hairy sea monster" washed up on the Pacific coast and netizens were speculating if it was a "giant furry octopus," or a "woolly mammoth."
