Delete the rules “Theft”, “Returning Nouns”, and “Removing Nouns”.

Add a new rule called “Exchanges” with the rule text:

Exchanges manipulate the noun content of the Katamari and/or the inventory. Actions that count as exchanges include:

• Steal: If a Prince’s Inventory is not full, they may pay X (where X is less than 10) stamina to remove from the Katamari, the item at position (Katamari Size - X), and add it to their inventory. When they do this, they must also re-number all items.
• Return: By spending one stamina, a prince can remove a noun from their inventory and add it to the end of the Katamari’s contents. This increases the irrollability of the Katamari by 1.
• Remove: A prince may pay 1 Stamina to remove a noun from the Katamari that is not the name of a Prince. This also increases the irrollability of the Katamari by 1.
