It's a Curly Tail, it's a leach, it's weedless, it hides the hook and has great action.
The G Grub is a Hybrid from Mister Twister, the company that created the Curly Tail.

The dual parallel dorsal fins that run the full length of the body flutter and wave like a leach. They also serve the dual purpose of helping to make the G Grub weedless and hide the hook point while leaving it exposed for easy hook sets. The classic Curly Tail design is incorporated into the G Grub as well.

A multi-species bait that is versatile and guaranteed to offer plenty of action.
