Mechanics Manual

The rules are not background — they are the silent dialogue between the level designer and you.

Flagship mechanic

Pride Skill Tree

Earn 1 Pride point for each cleared stage. Challenge and Bonus modes grant extra points. You can reset allocations freely at any time.

The full interactive Pride skill tree allocation calculator is available in the frontend only. Visit the page to use the draggable point slider and three-column tree view.

Consumables

Consumables are purchased with Pond Crystals at the Snowbloom Palace B shop. Each purchase grants multiple items, consumed only on victory.

NameCostQtyEffect
Wall-nut Bandage150 PC1×Place a Wall-nut onto an existing Wall-nut to repair it. Repair amount depends on the placed Wall-nut's remaining HP.
Emergency Sun Bottle15 PC10×Once per battle: immediately gain 150 sun. Designed for night or indoor levels where sun sources are scarce.
Typhoon Fan20 PC12×Once per battle: push back all zombies in one selected row by a fixed distance. Contributed by Hurriclover.
Collection Magnet10 PC15×Automatically collect all sun and Pond Crystals on the field — no manual clicking needed. Designed by BISHOP, inspired by Magnet-shroom and Sunflower.
Apple Compound Fertilizer15 PC10×Significantly reduce the sun cost of the Apple Clock's time-switching ability. Formulated by Power Peony from Apple Chordus's research.
The Pond1 PC8×Up to eight per level: an energy drink that invigorates plants. Power Peony's personal favorite—Wiremoss describes it as 'disgusting.'

Sunflower Matching

Sunflower matching is a core economy subsystem, reworked in 0.17p. Adjacent Sunflowers can be matched in a line; match direction no longer affects the result.

3

Burst of sun

Three adjacent Sunflowers in a row or column produce instant sun for the two retained plants. Ideal for kick-starting your economy early.

4

Double-speed Sunflower

The center Sunflower retained after a 4-match produces sun at double speed. This state can be inherited through subsequent matches.

5

Twin-production Sunflower

The center Sunflower retained after a 5-match enters Twin state, producing two sun drops at once. This state can also be inherited.

Crossbreeding

Peashooter is currently the only crossbreedable plant in the Field Guide. During crossbreeding, you can inspect the A, B, D, and F gene loci; dominant alleles determine the offspring's traits.

GeneTraitDescription
APea type / elementControls the pea's base type. Different allele combinations produce normal, ice, or fire peas.
BPea sizeAffects the collision volume of fired peas. Larger peas hit more easily but may be blocked by obstacles.
DThree-lane / scatterControls whether the plant fires in three lanes, or the scatter angle distribution of peas.
FAttack speedAffects base attack speed. High-speed alleles significantly boost DPS while per-shot damage remains unchanged.

Terrain Interactions

3×3 (default) / 5×5 (Corchid-boosted)

Liquids & Smoke

Hygro Plantago absorbs nearby liquids and converts them into effect smoke. Different liquids produce different smoke — lava burns, puddles slow, honeydew attracts.

  1. 1Click Hygro Plantago to absorb liquids in its 3×3 area. If planted on a Corchid, absorption expands to 5×5.
  2. 2The absorbed liquid is converted into effect smoke covering 3×3 (or 5×5), applying the corresponding effect to zombies within for the duration.
  3. 3After Magnet-shroom removes a bucket, it can pass the bucket's liquid to nearby Hygro Plantago or CocoBottle Shine — enabling cross-system synergy.
  4. 4Honeydew, rotting honeydew, and swamp fluid vanish upon entering water and cannot form smoke on water surfaces.

Magnetism System

Magnet-shroom is the core of the magnetism system, removing metal objects and passing them to plants that can use them. Mechanical Snowfield is 'the kingdom of electricity and magnetism,' and its enemy design is built around this system.

  1. 1Magnet-shroom can remove buckets, poles, firefly lamps, lanterns, and certain metal head armor from zombies.
  2. 2When powered Wiremoss is adjacent to Magnet-shroom, its cooldown is halved.
  3. 3Removed metal is passed to nearby plants that can utilize it (e.g. CocoBottle Shine). If no receiver fits, it is thrown as a projectile.
  4. 4Magnet Truck Zombies attract nearby projectiles. Magnet-shroom can temporarily disable them. In the BISHOP fight, when all Magnet Trucks have been continuously controlled for 16 seconds, BISHOP destroys every Magnet Truck on the field.
  5. 5Since 0.17o, Magnet-shroom can absorb metal projectiles (Charm Staves, lanterns, thrown items from other Magnet-shrooms), but only when the projectile targets Magnet-shroom's faction.

1 tile (4 corners → 1 planting spot)

Swamp Grid Points

Corchid can only be planted on tile corners. Four Corchids occupying all four corners of the same tile convert it into a plantable tile — ignoring swamp and liquid restrictions, and buffing swamp plants placed on it.

  1. 1Corchid can only be planted on tile corners. A tile has four corners, requiring four separate Corchids.
  2. 2Once all four corners are occupied, the tile becomes immediately plantable, bypassing swamp, liquid, and certain terrain restrictions.
  3. 3Swamp plants (e.g. Lorus, Honey Bamboo, Hygro Plantago) planted on the generated tile receive attribute bonuses.
  4. 4Click-and-drag Corchid to plant in batches, at the cost of extra sun and longer recharge per plant.
