The chocolate will come in special edition £1 sharing bags, so you'll want to get down to the nearest supermarket as soon as possible!
What makes them different from the original Smarties then?
In the special edition bags, the colours will be changing to pastel shades of pink and blue, the perfect edible gift for any hardcore unicorn fans you might know.
Smarties are now one of several companies to have unleashed special unicorn-related items onto the world. This year we've seen brands selling everything from unicorn-themed homeware to Mr Kipling cake slices. You can even find six foot giant garden sprinklers and unicorn snot suncream for all of this sunny weather we're having.
