Mysterious, smelly blobs washed ashore in Virginia Beach over the weekend.

The Virginian-Pilot reports that the softball-sized, blackish to grayish lumps were spread along about a half-mile stretch of Chic’s Beach by Saturday evening.

This isn’t the first time foul material washed ashore this summer. Smelly specimens turned up on Chesapeake Bay beaches in July. Health Department officials said they couldn’t identify them because no one saved a sample, but it’s possible that they were skunk sponges.

The malodorous blobs didn’t stop people from playing at the beach Saturday. Children ran in and out of the water, and some people sat on the sand close to the blobs, as if they didn’t exist.
