Sometimes there easy to miss because of where the pop up I almost missed a feather because it was laying on the little work table of the hospital and another time I had a feather laying on the floor of the lab really close to the bamboo wall where the villagers enter and exit. Also there have been several times that they have showed up behind the trees including the tree that drops fruit. The only reason I knew they where there was the sparkle rose above the tree never saw it till I dropped a kid on the sparkle and they came from behind with it in their hand.
