Raymond Chandler III
That answers my original question but brings up another. In the rules it says "If players have two or more Guilty Pleasures matching a Leader’s Guilty Pleasure Type, they may ignore both Minions listed on the Leader’s associated cost. Regardless of any Guilty Pleasure discount, players must still always pay one Minion to steal a Leader."
I took that to mean that if you have two Guilty Pleasure cards that match the Leader, you ignore the icon and pay one minion of any type. Meaning that in your example you can choose to pay a zombie instead of the listed Goblin or Demon if you have 2 Chef's Hat symbols.
That is correct. The additional minion to overtake a leader position is always "wild" and can be a minion of any type.
