Called Goth Holiday and shot on location in Blackpool, the ad will run until the end of July on terrestrial TV channels across Scotland and on satellite channels nationally. It will also screen in cinemas from July until the end of September.
Outdoor poster ads and PR activity featuring the goth characters will back the launch.
Adrian Troy, head of marketing for Barr Soft Drinks, said: "The new advert presents an alternative take on the traditional summer holiday theme with some very entertaining results.
"We've had some playful fun with the beach experience and the characters involved to show that I rn-B ru is the perfect way to uplift your mood and make the most of the summer months."
