The flat surface on the head of this fly pattern makes a nice disturbance in the water when stripped gently. Let the Peeper Popper sit and then strip once. When you can hear the gurgle, then you're doing it right and the panfish and Bass will hear it as well. Smallmouth bass love these fly patterns. Fish it early or late when the water is dead calm.
