Colin the Caterpillar is a firm favourite at birthday parties.
Whatever age you are, everyone has fond memories of cutting into the animal-themed chocolate log and enjoying a slice with friends and family.
The popular range has expanded over the years and now includes a Connie the Caterpillar cake, jelly sweets and mini logs too.
You can even personalise your caterpillar cake with a special message, or buy Halloween and Easter-themed versions.
Now M&S has announced a new addition to the range.
Fans can now buy mini chocolates with Colin's face on them.
They're made with white and milk chocolate.
The new treats were spotted by Instagram food blogger @newfoodsuk.
You can find them in stores now and each bag costs £2.
If you have a birthday coming up, you can also buy a special Colin the Caterpillar gift set.
For £20 you will get a cake, some veggie sweets, a balloon and a tote bag.
