Y2K

The Y2K—often called the Y2K Bug or Y2K Worm—is a bright, attention‑grabbing pattern that rose to popularity around the turn of the millennium. Built from a fluorescent foam egg or ball threaded directly onto the hook, it delivers maximum visibility and a bold profile that trout simply can’t ignore.
Highly effective in clear water and high‑visibility conditions, the Y2K remains a regional favorite across parts of the United States where egg‑style attractors consistently produce. Love it or hate it, this simple pattern catches fish—and plenty of them.
