Monster Munch 'Geoffrey Hayes' by Frank PR

Ex-children's presenters Geoffrey Hayes from 'Rainbow', Timmy Mallett, Pat Sharp and Dave Benson Phillips have all recorded appeals to find the original Monster Munch monsters who have gone missing.

The celebrity appeals direct people towards Walkers' website, where a £5,000 prize is up for grabs.

The appeals are part of Walker's wider campaign to rejuvenate the Monster Munch brand.
