Fuzzy dice / dice bait
If somebody says “fuzzy dice” in the traditional sense, this is usually what they mean: a small cube or chunk center with skirt material, rubber strands or fine appendages running through it.
Urchin bait
Usually this means a round center with arms going every direction. Some are tiny finesse baits; others are big enough to fish on much heavier gear. “Urchin” is becoming one of the clearest names for that round branch.
Spiky ball
This is probably the easiest plain-English name for the round Urchin-style profile. Say “spiky ball” and most fishermen can picture the bait before you even show it to them.
Coike / Coike-style
Coike is strongly associated with Hideup's product family and the Japanese roots of the modern urchin craze. It is useful context, but it should not be treated as a generic category name for every maker's bait.
Fuzz ball / ball of fuzz
This is looser slang rather than a standardized product class. It works as a broad description because both dice and urchin branches share the same visual idea: a compact center wrapped in motion. Bassmaster used “ball of fuzz” in 2026 coverage of the craze.
Why the names overlap
The baits got popular faster than the names got organized. Japanese-origin baits, U.S. tournament coverage, retailer labels, manufacturer product names and angler slang all arrived at slightly different words for related ideas. That is why search results for one term routinely show more than one physical profile.
