Colin the Caterpillar - arguably the nation's favourite birthday cake (no matter your age) - has turned 30 years old.
To celebrate, Marks & Spencer has set up a Colin the Caterpillar Instagram account and is selling a bumper Colin celebration pack - with a cake, mini chocolate Colin faces, mini cakes and three packets of Colin sweets.
While he may have graced party tables across the country for the last 30 years, how well do you know the supermarket's smiling caterpillar cake? Here are 13 facts you (probably) didn’t know.
He's popular with celebrities
David Beckham and Dame Judi Dench have celebrated their birthdays with Colin the Caterpillar cakes.
Apparently former Prime Minister, David Cameron has a 'love affair' with the famous critter cake.
He has a big entourage
It takes a team of 47 people to lovingly make each Colin cake from start to finish.
His look has changed over the years
Those who remember Colin in the 90s will notice that he looks a bit different now, with a changed face and the addition of white chocolate feet.
He's got a signature style
Colin has six white chocolate feet and 15 colourful milk chocolate sweets on his back.
Each year, M&S uses 8.4 tonnes of chocolate sweets to decorate Colin with his signature markings.
Colin and Connie married in 2017, and Connie was introduced to the M&S cake range - followed by mini Connie cakes, to go alongside the mini Colins.
Connie is a milk chocolate-coated chocolate sponge roll, but instead of being filled with chocolate buttercream like Colin, she's filled with strawberry buttercream and decorated with pink chocolate sweets.
With a couple of kids, of course
M&S sells 1.4 million individual mini Colins and 1.6 million mini Connies every year.
He's very popular
The retailer sells over 450,000 Colin the Caterpillar cakes - and over 175,000 Connie cakes each year.
There have been Christmas and Halloween Colin cakes
Yes, Colin has had a festive and spooky makeover for Christmas and Halloween.
Halloween Colin launched last year, with a green face and chocolate 'maggot' decorations.
Festive Colin became the ultimate Christmas treat, as M&S sold over 175,000 of the limited edition cake last year.
He supports charity
In September 2019, M&S sold over 85,000 Macmillan Colins and mini Colins - with 10 per cent of each sale going to the charity.
He's big in Kent
Party animals in Kent love Colin the most, as he's bought more there than in any other region.
Connie is most popular in Cheshire, and Londoners love the mini caterpillars. Waterloo commuters buy the most mini Colin and Connie cakes.
You can buy Colin all over the world
Colin cakes and sweets are sold in 17 countries overseas. The United Arab Emirates sells more Colin the Caterpillar cakes than any other destination, closely followed by Hong Kong.
The French love the Colin sweets the best, as over 60,000 bags are sold there every year.
He's probably taller than you think
Stacked face to bottom, it would take 1,108 Colin cakes to reach the top of the Shard in London.
He's a trendsetter
Fans of Colin can try Sainsbury's Wiggles the Caterpillar, which launched in 2011. At that time, Asda launched Bonnie and Clyde the Caterpillars, as well as a free-from caterpillar cake, Frieda.
In 2015, Waitrose joined the caterpillar cake brigade, though theirs had no name.
In 2017, Tesco added to their caterpillar range with a free-from cake called Carl.
