|Card from the original Weetabix promotion|
It was so popular, they did it twice with the TV Time Lord and ran similar promotions with Disney characters, Asterix and one for Star Trek The Motion Picture.
Here's something I knocked up based on the second Doctor Who promotion. Each box of Weetabix contained four figures - three 'monster' cards and a "Secret Message From Time Lords" (sic). The monster cards could be slotted into one of four game boards that adorned the back of each pack and became forfeits for landing on specific squares during game play.
My little effort follows the same format but with modern EastEnders characters instead... Playing the game makes an exciting alternative to having to watch the series at the moment...
You could also try to decode the secret messages from Mr. Papadopoulos... if you really want.
