国王宝宝#472

King Baby is an unlockable passive item added in The Binding of Isaac: Afterbirth †.

• King Baby references the official Binding of Isaac tarot card set, in which ??? represents the Emperor.
• Its main Item Pool being in Shops may reference "king cakes", a Christian tradition of having a cake with a baby figurine inside for Mardi Gras or the Feast of the Epiphany.
• It can also be a reference to the Spanish "roscón de rey", a traditional Epiphany cake that contains a hidden figurine of one of the Three Wise Men (also known as the Three Kings). The person who finds the figurine is symbolically crowned “king” for the day, reinforcing the royal theme associated with the item.
• The Steam achievement description for unlocking King Baby says "Unlocked a new co-player baby," despite it being an item.
• Before Repentance, King Baby's pickup quote was "Lord of the dead!".
• King Baby's pickup quote is a reference to the film Army of Darkness, where the protagonist Ash says "Hail to the king, baby!". Familiar Modifiers Items
