Add a new subrule to the rule “Attraction List”, call it the “Double Dunk Tank” and give it the following text;

The Double Dunk Tank is a Queue. While in the Double Dunk Tank, Visitors’s Groups may privately message the Proprietor to declare the Visitor’s intent to do one of Cover or Dunk - their Tank Action is their last intent thus messaged while the Traffic Light was Green, or Cover if their Group never sent such a message.

The Double Dunk Tank’s front effect consists of several steps:
* First, choosing the first Visitor in the queue and the next visitor who isn’t controlled by the same group as the first as the turn’s Sitters. If this selection cannot be made, skip the rest of the Front Effect.
* Each Sitter who chose Dunk Drenches the other Sitter, and each Sitter who chose Cover Protects the other Sitter.
* Finally, move the Sitters and all Visitors between them in this Queue to the Plaza.

Add a subrule “Dunker’s Dilemma” to the rule “Stamps”. Give it the following text:

A Sitter in the Dunk Tank who is Protected receives a C stamp for gaining the trust of their fellow.
A Sitter in the Dunk Tank who Drenches the other Sitter while being Protected also receives the coveted D stamp for their mastery of deception.
