‘What the hell is that?’: What the hell are all those big balloons?’

A photo of a large balloon apparently made of cardboard and some other materials has been circulating online since Friday morning.

A user posted a photo on Twitter, claiming the image showed what it claimed was a giant balloon being filled with “all the right stuff.”

“This is what the balloon looks like,” the user wrote.

“I’m afraid I don’t know what it is or where it came from.

I just got it.

All right.

I’m going to have to leave it up for another day.”

A second user, who has also tweeted the image, tweeted that it was made by the company’s parent company, Costco, and was “a giant balloon made of some cardboard and a little more stuff.”

A third person on Twitter claimed to have seen a “big balloon” being filled up with “everything from peanut butter to jelly beans.”

Costco has not commented on the image or said if it’s authentic.

“I’m sure there are people out there that think that’s a hoax,” Costco spokesman Brian DeMars told ABC News.

“But we are confident that what we’ve seen is accurate and is not an intentional hoax.”

Costso’s parent, ConAgra Foods, did not immediately respond to ABC News’ request for comment.
