Each night, the Magician chooses a Minion: if that Minion & Lil' Monsta are alive, that Minion babysits Lil’ Monsta.
The Marionette neighbors a Minion, not the Demon. The Marionette is not woken to choose who takes the Lil' Monsta token, and does not learn they are the Marionette if they have the Lil' Monsta token.
