A minion transferred to Donut's personal ownership, enabling her to make clockwork copies of him.
Princess Donut invoked Clay-ton as precedent when she proposed building a Clockwork Bomo: Bomo is currently a Royal Court Minion belonging to the party, and would need to be switched over to a minion of hers alone, just as they did with Clay-ton and Very Sullen. Only personally held minions can be duplicated by her clockwork ability.
One of Donut's personal minions and the model for how minion ownership is reassigned.
