Add the following sentence to the end of the second paragraph of rule Carrying:

If the rule “Party Time” or one of its subrules would transfer possession of the Rubber Ducky to a Partygoer who already holds four Objects, that Partygoer first drops their first-listed held Object to make room for the Rubber Ducky.

In the rule Carrying, change

any other Partygoer at the same Party or Grand Party

to

any other Partying Partygoer at the same Location

In the rule Pot Luck, change

start holding the Objects “Soda”, “Meat”, “Chips”, “Brownies”, or “Acoustic Guitar”.

to

start holding the Objects “Soda”, “Meat”, “Chips” or “Brownies”, which are categorized as Food, or “Acoustic Guitar” which is categorized as an Instrument.

Add a subrule to the rule Locations called “Local Objects” and give it the following text:

This rule only applies to Partying Partygoers except where it explicitly says otherwise.

A Partygoer who enters the Pool with a Food Object ceases to be holding that Object.

A Partygoer who enters the Pool while holding the Rubber Ducky chooses a random Partygoer in the Pool and, if they didn’t choose themselves, transfer the Rubber Ducky to that Partygoer.

The Bathroom has a Stash, a publicly tracked list of Objects. Partygoers alone in the Bathroom may transfer Objects they’re holding to the Stash or remove Objects from the Stash to start holding them. While the Rubber Ducky is in the Stash, the last Partygoer (whether Partying or not) to be Holder of the Rubber Ducky remains Holder of the Rubber Ducky. The Bathroom Stash empties after each Party is resolved.

A Partygoer who is in the Kitchen and not holding any Objects may start holding “Soda”.
