Donut's proposed clockwork duplicate of Bomo, built to carry the bomb so the real minion survives.
Objecting to Bomo being used as a suicide bomber, Princess Donut asked what if she made a clockwork Bomo. She explained that Bomo is currently listed as a Royal Court Minion of the party, and that he'd have to be switched over to a minion of hers alone — the same thing they did with Clay-ton and Very Sullen — before her ability can produce clockwork versions of him. She scolded Carl for not paying attention to how the party system works.
Carl's worry was whether a clockwork copy would exit through the correct saferoom door; Donut told him he underestimates her and that she has it handled, with the one catch that she must be inside the Saferoom herself when they do it. They agreed to prepare the real Bomo as a fallback, and to do it Donut's way if they reach the next town within three hours.
An unbuilt duplicate as yet — a clockwork facsimile of the minion, of the sort Donut has produced from her other minions.
Donut's humane workaround for delivering the bomb without losing a friend.
