Die Kürbiskopf-Bande (2002)

From Bruno Faidutti's site:

Points are now candies, and secret agents are Halloween children going from door to door, asking for sweets. The Pumpkin head gang is the lighter children's version of Heimlich and Co. In this clever adaptation, the bluff element is replaced with some memory - each player must remember where his pawn is and moves, since the colors of the pawns are hidden and cannot be looked at after the game has started.
