Editing Round 9/Ruleset (section)

== Ponds ==
There exist ponds in the land. The number of ponds is initially equal to the number of ducks in existence, divided by four and rounded down. Whenever a new duck is created, any player can roll a d6. If the result is 6 then a new pond is created.

Each duck lives in exactly one pond, or its pond is unset (which is the default case). Any duck that does not live in a pond may be assigned a pond at any time by its owner by posting in #game-actions. The duck immediately moves to that pond.

Players may move ducks from one pond to another by spending one quack from that duck and posting in #game-actions. Players cannot move a duck (after its initial assignment) that does not have any quacks. 

Pond is an essential duck attribute.
At the beginning of each voting period, each duck loses one quack for each duck of its same color in the pond it lives in, not including itself. It also gains one quack for each duck of a different color that lives in that pond.

Ducks on scouting missions cannot change their pond assignment, except to be assigned one.
