Larry jumps with joy and claps like a small child. He presents to Martin his own moth, which seems more normal. It doesn't stick to him or make him itch, but it'll be with him temporarily (or not, depending on preference). It seems pretty determined to show Martin something though, so it'll keep fluttering around him until he follows it. It brings him to the evening primrose, and alights on the flower, as if satisfied its own mission. On picking it, if Martin applies the juices from the stem to the itchy spots on his skin from the moth he'd brought Larry, it'll soothe that. It'll also help with bruises, minor injuries, and other sorts of skin inflammation.* If he picks some and comes back the next day, he'll find that there will be more, just for him. If others haven't done the quest and attempts to pick it, it'll wither up until Martin himself picks it.

(*Mods are aware there aren't any actual proof of medicinal uses for it, but just using it for rp's sake)
