Frog Factory The Mongrel Frog - The Mongrel from Frog Factory is going places no walking bait has ever gone. A hybrid bait, the Mongrel is a cross between a traditional walking bait and a hollow body frog. This allows it to work in heavier cover than traditional walking baits ever have before. The Mongrel also features loud internal rattles that call fish in through heavy vegetation. To top it off, the Mongrel comes in 6 killer colors and sports a premium, heavy duty frog hook to pin them in the thickest stuff you can throw it into.
