Which type of bait is known for its cupped-nose design to generate sound and action on the water's surface?

Popping baits are specifically designed with a cupped-nose shape that helps create a distinctive "popping" sound when retrieved across the surface of the water. This action simulates the movement of prey and can effectively attract fish, particularly during feeding times. The cupped design increases water disturbance and noise, making it easier for fish to locate the bait from a distance. This type of bait is particularly effective in drawing attention in various conditions, especially in calm waters where the additional noise and movement can entice nearby fish.

Walking style baits focus on a side-to-side motion to mimic the movement of struggling prey rather than creating sound. Frog-style baits imitate frogs or other surface-dwelling creatures, while weedless surface spoons are designed to navigate through vegetation but do not produce the same popping action. Each of these alternatives serves different fishing strategies but does not offer the unique sound-producing feature that makes popping baits particularly effective.
