Walkers relaunches Monster Munch Crisps

Following the successful revival of Cadbury's Wispa chocolate bar, which was re-released last year in response to reportedly overwhelming consumer demand, the lurid corn snack has been reborn.

And Walker's Crisps, which manufactures Monster Munch, has also taken a lead from Cadbury in coming up with a clever advertising campaign with which to promote the crisp.

The company has discovered that it cannot find three monster puppets that it used in advertisements for the snack in the 1970s and 80s.

Now, in a high-profile advertising campaign, it is offering consumers a £5,000 reward if it can find them, and wants people to report possible sightings to its website, findourmonsters.com .
