Start in Japan, not with the latest U.S. launch.
This story did not start with one American product launch. Japanese anglers had already been using unusual compact baits with skirt strands, appendages or all-direction motion before the profile became mainstream in the United States.
The exact age depends on which branch you are talking about. Bassmaster's 2025 Coike review described the Hideup Coike as having a prominent Japanese-market role for a couple of decades, while Major League Fishing's 2026 retrospective described the Coike as catching fish in Japan for about a decade. Those accounts differ on the exact timeline, but they agree on the important point: the Japanese lineage substantially predates the American boom.
“Fuzzy dice,” “Coike,” “urchin,” and “spiky ball” are not one continuous product family. They are overlapping ideas that arrived from different makers and were later grouped together by U.S. anglers, retailers and media.
Around 2022: U.S. pros start acting on Japanese tournament intel.
Major League Fishing reported in 2026 that Alton Jones Jr. first got a Coike around 2022 after being told the bait had started winning tournaments in Japan. At first, the shape was so unfamiliar that even experienced pros were still figuring out how it wanted to be rigged.
That is worth remembering: the bait showed up before anybody here had a settled playbook for it. Guys had to figure out the rigging as they went.
2024: the “okay, this is real” moment.
Michael Neal's St. Lawrence River victory using a homemade fuzzy-bait contraption became one of the defining U.S. moments. It reinforced what Japanese-influenced anglers had already been exploring: these strange strand-covered profiles could produce under real tournament pressure.
By then, the term “fuzzy dice” was broadening. Major League Fishing's own coverage grouped square, spherical and other protruding-strand baits under the same general conversation.
2025: manufacturers and media turn fuzzy baits into a recognizable category.
Major League Fishing described fuzzy dice as one of the hottest new games in bass fishing and pointed to the OSP Saikoro Dice Rubber as the bait that helped give the category its name. The same coverage also included spherical and other non-cube shapes in the broader family.
Bassmaster's 2025 ICAST coverage showed another signal: U.S. companies were no longer merely importing the idea. They were actively designing their own fuzzy products, experimenting with strand placement, salt, buoyancy and body shape.
2026: the Urchin / spiky-ball branch becomes the headline.
By early 2026, Bassmaster was explicitly describing two main branches: soft-plastic dice styles and round “urchin” or “spiky ball” styles. At the Lake Martin Elite event, spiky balls were showing up regularly on front decks and anglers were testing weightless, Neko, drop-shot, Tokyo-rig and treble-hook approaches.
By summer, Major League Fishing was calling the Urchin craze one of the hottest stories in bass fishing and reporting a rush of new products and terminal-tackle ideas. ICAST 2026 coverage confirmed the same direction: urchin baits were everywhere.
So where does that leave us now?
The family is no longer one novelty bait. It is becoming a design system: compact center body, motion in multiple directions, unusual fall or hover behavior, and increasingly specialized rigging.
- Dice/fuzzy-dice remains the recognizable finesse branch.
- Urchin/spiky ball has become the dominant round-profile branch.
- Hybrid fuzzy baits are starting to blur center-body shape and material rules.
- Micro profiles are creating overlap with crappie, panfish, trout, BFS and ice fishing.
- Dedicated terminal tackle is developing around the category instead of forcing every bait onto old hardware.
