@coriander do the fishing for trash board quest and Linus will give you the fiber seeds recipe. they need to be watered so grow them in winter when your sprinklers have nothing else to water anyway. (save up mixed seeds they're an ingredient)
@Taweret I've tried to do that quest before but actually catching trash can be weirdly hard sometimes =P
@Taweret @coriander you csn also use the little body of water outside the spa
