The hierophant ends up at the cabin and attempts to attack Pep but fails because he can’t enter the house. Pep accidently reveals the other threes location while poking fun at the hierophants traditional nature…
He finds them and Jake turns into a house to protect the others. Marcie and The Hierophant have a nasty fight resulting in Marceline being poisoned pretty bad by a scorpion formed hierophant. Eventually he’s defeated by pushing him into house Jake, because of his traditional values he poofs, giving Marcie his shapeshifting ability.
Because of The Hierophants poison Marceline is very very ill and needs the power of The Moons healing abilities to help her. Finn and Jake are instructed to take her back to Peppermint butlers poison lab but mistakenly hear “stake her back” which causes some funny shenanigans but also result in The Moon waking up because of them attempting to stake her the entire day but failing because of her instant healing.
