Firefly Zombie

The lamp holds cold fireflies. One is manageable; many are trouble.

Lore

Firefly Zombie's lamp contains specially bred cold fireflies, and it releases one every so often. The fireflies spiral toward plants and freeze them. They look fragile, but can surprisingly take about 25 peas.

If they were not so cold, those fireflies might be nice to touch. What a pity. To deal with them, use their attraction to light; Opti-caltrop's light orb draws fireflies in.

Mechanics

Role

Backline summon · Freeze interference

  • Durability: about 20 peas; slow speed.
  • Periodically releases cold fireflies.
  • Fireflies have about 25 peas of durability and fly toward plants to freeze them.
  • Opti-caltrop's light orb attracts fireflies and can be used to pull them away.

Advanced mechanics

Firefly Zombie is dangerous less because of its bite and more because its lamp keeps adding independent cold fireflies to the field. Read it as three linked pieces: the source body, the removable lamp, and flying fireflies with their own durability and targeting. Removing only the source leaves released targets behind; clearing only fireflies lets the lamp keep replenishing them.

Body, lamp, and release timing

Firefly Zombie's body is best read as about a 600 HP maximum target; the shorthand durability in the main entry corresponds to roughly 400 HP of work to the critical window. Its walking speed is slow, but the lamp converts backline time into new flying targets, so it should not be counted like an ordinary slow walker.

Release is not a passive aura. It is a lamp-state timer event: after an initial preparation countdown, each lamp opening creates one cold firefly and sets the next release timer. A released firefly is an independent target and must be handled separately.

Hsource,max≈600 HP,Hsource to critical≈400 HP,Hfirefly=500 HPH_{\text{source,max}}\approx600\text{ HP},\quad H_{\text{source to critical}}\approx400\text{ HP},\quad H_{\text{firefly}}=500\text{ HP}
The lamp is the continuing release switch; body, lamp, and released fireflies must be handled separately.

Flying firefly and cold resolution

A cold firefly is not a normal one-use projectile. It has 500 HP of its own, seeks valid plants on the field, and approaches along a curved path. Ordinary single shots do not solve it the way they would intercept a small projectile.

On plant contact, the firefly resolves cold onto the target and remains a board problem after a short pause unless it is removed by damage, pulled to a controlled light source, or prevented from being replenished by stripping the source lamp.

F(t+Δt)=F(t)+v Rϕ(P−F(t)^)Δt,ϕ≈60∘F(t+\Delta t)=F(t)+v\,R_{\phi}\bigl(\widehat{P-F(t)}\bigr)\Delta t,\qquad \phi\approx60^\circ

Light-seeking target and Opti-caltrop bait

Without a light source taking over, fireflies seek valid plants that can receive the freeze pressure. Opti-caltrop's light orb rewrites that choice and pulls fireflies toward the illuminated point; this is the central reason Opti-caltrop solves the firefly problem in Mysterious Swamp.

Baiting is not immunity. A pulled firefly still has independent durability and still resolves cold on contact. The difference is that the freeze pressure is concentrated at a more controllable location. Opti-caltrop's laser is ray-based, so this cold interference usually costs less than it would against ordinary firing plants.

The orb pulls freeze pressure away from core plants, but the firefly itself still needs cleanup.

Magnetic lamp removal and tactical reading

The firefly lamp is a special metal target that Magnet-shroom can handle. Once Magnet-shroom removes the lamp, Firefly Zombie loses further release ability. If an Opti-caltrop is nearby, the lamp can also be passed to it and converted into temporary laser-cannon-style external fire.

The correct order depends on how many flying targets are already present. If few fireflies have been released, pressuring the source or stealing the lamp prevents the problem from snowballing. If several fireflies are already active, stabilize with light bait and area or high-frequency cleanup before returning to the source.

  • Remove source: cleanest before many fireflies are released, preventing future flying targets.
  • Clear fireflies: urgent once they have accumulated; each 500 HP target is independent.
  • Light bait: concentrates cold resolution at a controllable point and protects core plants.
  • Magnet-shroom: lamp removal stops further releases; a transfer to Opti-caltrop creates a short counterattack.
Stable handling usually combines source control, light baiting, and flying-target cleanup.
