The Coike Thunder Elastomer (by Hideup) is a Japanese finesse creature-style soft bait designed for ultra-subtle, high-pressure bass fishing situations.

It’s part of the broader “Coike / Coike Thunder” lineup, known for its “urchin-like” profile and heavy use in modern finesse presentations.

What it is

The Coike Thunder Elastomer is a solid-body elastomer bait with lots of fine, hair-like appendages that constantly move in the water even with little to no rod input.

  • Made from elastomer material (more durable and buoyant than standard soft plastic)
  • Dense “hair” fibers create continuous micro-movement
  • Compact, creature/urchin-like shape

Key action & behavior

  • Floats or suspends naturally when weightless
  • Appendages “pulse” and sway even at rest
  • Designed to trigger reaction bites from pressured bass
  • Very effective on pause/fall

How anglers typically fish it

It’s not a swimbait-style bait—it’s a finesse “hover and irritate” lure:

  • Weightless rig over grass or shallow cover (stays up and quivers)
  • Light Texas rig or free rig for controlled depth
  • Dropshot or nail-weight setups in finesse situations
  • Sometimes used with small hooks or even forward-facing sonar targeting

    Why it’s popular

    • Extremely effective in clear, pressured water
    • Works well when fish ignore traditional worms or jigs
    • High durability compared to standard soft plastics
    • Subtle “alive even when still” motion is the whole appeal

    Size context

    The Thunder series comes in multiple sizes (S/M/L), with the Thunder models typically around ~2 inches
