The agency, which released new TV ads for the brand at Christmas, has created a game which turns the shelters into touch-screen fairground stalls.
Travellers must bash as many digital falling eggs as possible in 20 seconds, in order to release their goo.
The new interactive ads will appear at bus shelters in London, Birmingham, Glasgow, Manchester, Nottingham, Sheffield and York.
All media for the campaign has been planned and bought by PHD.
