The Shimmy Frog is a great choice for catching bass on a fly because of its lifelike appearance and action. When at rest, this fly sits at about a 45 degree angle with the eyes at the surface just like a real frog. When a real frog gets frightened, it dives and swims away. This fly does the same, but with an added shimmy and shake as it dives towards the depths. Bass find this presentation irresistible!
