The campaign, based in the fictional town of Four Ridges, sees an evil little girl, Martha, unleash an unstoppable flood of Frijj.
The series of virals, reminiscent of cult film The Blob, will be released on 14 July.
Jon Williams, chief creative officer at Grey London, said: "Frijj is a slow drink, to be savoured and very different to the freneticism of a cola or energy drink.
"This is what we wanted the campaign to communicate but in a funny, engaging, off-the-wall kind of way."
A campaign website, www.fourridgesmustbedestroyed.com, will allow users to upload their own horror movies which use Frijj as a prop.
The best of these will then be showcased at a Frijj film festival across 25 London cinemas.
The digital campaign will be supported by online advertising as well as print and outdoor work.
