make sum soap (3 soapy/white herbs & boiling salt water)
use the person u plan on makin pure to put sum soap in the water (the pond near the research area it comes wen u clear the debris)
wen they finish cleanin bring em to the flute heads (once u put em there children r gunna keep comin sayin theyre interested in the flutes)
either finish building the nursery or hav sum1 constantly tell stories to the children (i told stories only cuz i didnt kno about the nursery) so tht they stay away
wen tht gets done put em over the whole in the tree and theyll do the rest
