Irn-Bru’s latest “mystery limited-edition flavours” were inspired by “genuine consumer descriptions” of the original drink, it tells us. However, its new ad duo claims to take us behind the scenes of the production of Nessie Nectar and Unicorn Tears.

On the shores of Loch Ness, Angus introduces himself as Irn-Bru’s official “Nessie milker”. Some amusing family photos and a set of gruesome “practice udders” complete the picture before we get to witness (sort of) his big moment.

It’s quite a jolt from amiable Angus to Kaleigh, the sharp-tongued psychopath charged with extracting unicorn tears for the other drink. She (verbally) uses both stick and carrot, giving the mythical creatures “your classic slagging”, but also flattering them into tears of joy or showing them slushy movies.

It’s original, funny and as Scottish as can be. What other brand could end an ad with the phrase: “Get it oot ya, ya big pink donkey”?
