The Chug Bug is an innovative topwater bait in several respects, which explains its longevity of production. Unlike many topwaters, both past and present, the Bug is a narrow, compact, and relatively short plug (2 1/2-inches long and 1/4 ounce, or 3 1/4-inches long and 3/8 ounce). This makes it ideal for fish with comparatively small maws, like smallmouths, spotted, white and striped bass. Such fish can more easily take a Chug Bug and are more likely to be hooked compared to some surface lures with more girth and length. The slimmer profile also makes for easier lure manipulation with light tackle, typical for smallmouths, spots, and other springtime targets.
