Milk.
If it's to get past the Gaping Plant, Cheese.... Literal Cheese.
How? Finish the Milk Farm renovations first to get a Cheese refinery.
Island is at the Upper Ark Gallery, you need to scare the Receptionist, and then Ruin a expensive statue, afterwards act as a placeholder. The Massive painting should be Open to Lust, by then.
