Although Easter has already come and gone, Saatchi & Saatchi London has launched a new campaign called “Goo On The Loose” that has people participating in a wild egg hunt.

The exciting campaign is to promote Cadbury’s Creme Egg Twisted, and has Internet users searching for an egg that has mysteriously gone missing. After signing up as a CIA agent (Cadbury’s Intelligence Agency) the game takes you through Google Maps while tips are sent via Twitter.

The winning prize is either a luxurious holiday in Morocco or a cash prize of $33,000.
