The work for Cravendale is part of agency's "catnapped" campaign. It features the return of mastermind feline Bertrum Thumbcat, brainwashing a milkman.
The "epic straws" promotion is giving away sets of straw packs. They contain a number of clear straws and coloured plastic connectors that can be adjusted to make different shaped and sized straws.
The on-pack promotion supplies consumers with a unique promotional code that can be entered on to a dedicated site, www.epicstraws.co.uk, created by Outside Line.
Consumers can choose one of three straw variations – "the secret slurper", "the cereal snapper" or "the bottle burglar".
Cravendale returned to TV last month with a second push for its "cats with thumbs" strategy.Follow @loullamae_es
