Tesco has said that it is 'extremely sorry' for labelling a fancy dress costume for Black Panther as 'Dark Panther', after people were left fuming on Twitter when they spotting the mistake.
The outfit was supposed to be a nod to T'Challa, the main character of what's being dubbed Marvel's greatest ever film, Black Panther. But despite the high profile of the new blockbuster flick, it seems Tesco had a little problem remembering the film that its costume was a reference to - naming the product 'Marvel Avengers Dark Panther Fancy Dress Costume'.
Naturally, it didn't take long for confused - and, in some cases, pretty angry - people to get themselves on social media to ask what the hell had happened.
Some people speculated that it was merely a publicity stunt, while some people just reckoned it was a simple mistake.
Others thought maybe it had something to do with Tesco not having the rights to use the film's brand for its product, or that it was the supermarket's own brand offering of a popular product. You know, like when Coco Pops become 'coco puffs' or Wotsits become 'cheese puffs'.
Mind you, the fact that the name still mentions a not-so-little-known 'Marvel Avengers' franchise, that seems slightly unlikely.

In a statement to Newsbeat, Tesco said: "This was a mistake and we are extremely sorry for any offence caused.
"We are correcting the description of this product on our website and are reviewing our processes to ensure this doesn't happen again."
Following its recent release, the film became an overnight success and is already the highest grossing film of 2018. Oh, and box office stats aside, it's even proven to be such a hit that it's caused a spike in the popularity of black cats, believe it or not.
The film was also the first Marvel movie to feature on the front of TIME Magazine, with Star Chadwick Boseman discussing in the accompanying interview why it's been such a firm favourite.
"You might say that this African nation is fantasy," the 40-year-old said. "But to have the opportunity to pull from real ideas, real places and real African concepts, and put it inside of this idea of Wakanda-that's a great opportunity to develop a sense of what that identity is, especially when you're disconnected from it."
Boseman added: "I know people are going to see this and aspire to it. But this is also having people inside spaces-gatekeeper positions, people who can open doors and take that idea. How can this be done? How can we be represented in a way that is aspirational?"
Director and co-writer Ryan Coogler added: "Obviously, the superhero is who puts you in the seat. That's who you want to see come out on top.
"But I'll be damned if the villains ain't cool, too. They have to be able to stand up to the hero, and have you saying, 'Man, I don't know if the hero's going to make it out of this.'"
