A woman was astonished after she discovered mysterious pink Wotsits in multi-pack bag of snacks.
Erin Leonard, was bemused after finding the bright-coloured crisp packs inside her purchase.
The 22-year-old care assistant of Bristol, made the discovery in blue multi-packs of the snacks.
She questioned if her unusual find meant she had won a mystery prize.
BristolLive reports Erin said: "I bought the first packet at a Co-Op in Bristol after working a 12-hour shift and feeling a bit peckish.
"I was a bit confused for a second, and then I realised that it was a pink version of the usual blue pack."
Wotsits were sold in a pink packet, when there was a prawn cocktail flavoured version of the popular crisp.
But the flavour was discontinued more than 20 years ago, although it made a return last year in 'giant' form.
Erin's pink packs of Wotsits had all the markings of a pack of 'Really Cheesy' flavoured crisps - and tasted like them too.
She said: "Then my mum went to the shops to get some the next day, opened the packet and they were all blue.
"I finished another 12-hour shift and went to the shop, bought another pack randomly and, as I was paying for them I opened them up and they were pink again!
It's just madness how two times I picked up packets that were pink and all of the bags are the same pink colour inside - there were no blue ones in there at all."
Erin's family were "in shock" when she showed them what she had bought and said none of them had ever seen anything like it.
She posted her discovery to TikTok and Facebook, where a number of people gave their thoughts on why the bags were pink.
One told Erin to keep the packets as "they might be worth a fortune", while another suggested "the ink has run out".
Another suggested the packs may have been pink "for Cancer Research". Erin did a quick Google search, but couldn't find anything to say this was the case.
The Mirror has contacted Wotsits manufacturer Pepsico/Walkers for a comment.
In 2020, Walkers launched a search for the biggest Wotsits Giant in the UK - and put up a £10,000 prize for the winner.
But there was a small condition that meant the customer who found it did not get to eat it.
Instead, the winning supersized snack will be collected to be put on display at its Walkers factory.
In return for your self-control, you could win a year’s supply of Wotsit Giants along with the £10,000 prize.
Karl Chamberlain, who works in quality control for Walkers, said at the time: "Wotsits Giants come in all shapes and sizes.
"On average, they are twice as large as classic Wotsits, measuring 6.5cm in length with a diameter of almost 2cm, but some fall outside of our average size margins.
"We call these ‘super Giants’ at the factory."
