ItzaBug has soft flexible rings that trap air, emitting tiny bubbles that imitate a live, breathing crawfish. Bass will hang on tight to the collapsible rings that feel like moving prey in the fish's mouth. Two flat appendages with pincers and the pair of curly-tail tentacles add a liveliness that bass will sense underwater. The movement is accentuated when the soft rings and body parts bump against grass and weeds, making it hard for bass to resist.
