For most of the past two decades, a hot new bass bait followed a familiar arc: a lure won a big tournament, anglers chased it for a season or two, then the craze faded. The lure cycling through bass fishing in 2026 is moving faster than any of them — and it looks like a hairy golf ball.
It is called the Coike, a sea-urchin-shaped wad of soft plastic with rubbery spines fanning out from a central core. Designed in Japan by the tackle company Hideup for the country's heavily pressured bass, it imitates nothing that swims in a North American lake. It is also, suddenly, the most dominant bait in the sport.
Over four weeks this spring, the Coike — and the wider family of "urchin" and "dice" baits now flooding the market — won three major events back to back. Canadian pro Chris Johnston took the Bassmaster Elite Series event at South Carolina's Santee Cooper Lakes with a 113-pound, 12-ounce four-day total, much of it on a Coike-style lure, with runner-up Brandon Palaniuk leaning on the same baits. Alex Davis banked $100,000 at the Lay Lake NPFL throwing one. Then Jason Christie sealed his 10th career Bassmaster Elite win with his entire rod deck rigged with urchin baits.
The puzzle is why fish eat it at all. "It's stupid how good they eat it here," tournament angler Ridge Faircloth said after winning a Toyota Series event on Lake Seminole on a Hideup Coike, telling In-Fisherman that nothing else compared.
Theories vary. Some anglers point to the bait's defensive look — when a bass closes in, the spikes splay out like a creature puffing up, triggering a reaction strike. Others note that the dense, spiky profile lights up on forward-facing sonar, making it deadly for picking off suspended, finicky fish. Veteran In-Fisherman columnist Joe Balog, a former national tournament pro, framed it as the latest entry in a long line of lures — from the Slug-O to the Senko to the ChatterBait — that catch fish precisely because they look like nothing in nature.
Not everyone is convinced the bait deserves all the credit. Writing for Sports Illustrated, Kurt Mazurek argued the Coike's tournament run may be partly a feedback loop. "I can't help wondering if the Coike was genuinely the best bait in all of those situations, or was it the most popular?" he wrote. "And because everyone was throwing it, is its success a self-fulfilling prophecy?"
Davis, the NPFL winner, makes a useful test case. He says his win was built on months of homework, not hype. "I got my first Coikes last fall," he told Mazurek. "I tried them a couple times but didn't really have any success. Then this spring, once I had some big schools of bass located, I thought I'd take the opportunity to see if I could figure out how to fish it to trigger bites." He won throwing it without forward-facing sonar most of the time — "just throwing it like a good old bass lure," he said.
Davis expects the spotlight to dim. "I think it will still have a place in my bait lineup for the next 20 years. I picture it like a wacky worm," he said. "There will still be a time and place every year where the Coike will be a great choice, it just won't be the only choice all the time, like it is at the moment." With so much focus on social media clicks, he added, "anything that shines for a tournament or two gets elevated and beat to death pretty quickly."
The scramble has created a genuine supply problem. The bait normally retails around $20, but with shelves bare and demand surging, unopened packs have been changing hands on eBay for as much as $284.98. Hideup has added smaller sizes, and brands including Berkley, Yamamoto, Hag's, Arsenal and 6th Sense have rushed their own versions out the door.
Hanging over all of it is a familiar question for tournament fishing: will somebody try to ban it? Mazurek raised the Alabama Rig restriction of the early 2010s and the ongoing fight over forward-facing sonar as cautionary tales. Davis is blunt about the prospect. "Honestly, I still don't understand why the Alabama Rig was banned," he said. "I suppose like everything these days, there will be someone who got beat by someone using a Coike and they'll start a campaign to get them banned. So I won't be surprised, but I don't think it makes any sense."
For now, the Coike has none of the usual triggers for regulation — no multiple hooks, no electronics cost, no obvious mortality concern. The likeliest outcome, most agree, is that pressured fish simply learn to recognize it. As Mazurek put it, in 20 years it will probably be "just another wacky worm" — a tool with its season, its place, and a lot less mystery.
