Sunflower Land — Season 16: Caves & Pigs (Operational Guide)

Introduction to Season 16

Season 16 (Chapter 16: Caves, Pigs & Weather) officially begins on November 2, 2026 in Sunflower Land. This major update shifts gameplay around three core interconnected economic pillars:

1. The Caves: Unlocked on Spring Island, featuring the new Myco-Composter processing machines, 25-tile excavation patches producing Wild Mushrooms, Magic Mushrooms, 4 tiers of Beetles, and Mud.
2. Pig Husbandry (Pigs & Pigpen): Level 1 to 15 Pigs, recurring Truffles harvests, Pig Bristles trade-ins, and Mud health/XP management (+25% final XP).
3. Dynamic Global Weather System: Non-stop rotation of 9 worldwide weather events (lasting 3 to 4 days each, completing cycles every ~27 to 36 days) with positive bonuses and seasonal threats mitigated through craftable protection gear.
4. Goblin Cave Merchant: Visiting vendor offering exclusive items for 48-hour periods, unlocked starting at Cave Tier I.

Step 2: The Underground Caves and the Myco-Composter

The Cave Entrance unlocks on Spring Island. Building the entrance gives access to the first subterranean chamber with one Myco-Composter machine and a dedicated 25-tile (5x5) digging grid.

Cave Access & Expansion Tiers

• Entrance Cost (Tier I): 200 Coins, 20 Wood, and 5 Stone.
• Expansion Path: Up to 8 levels (Tier VIII). Each expansion adds 1 Myco-Composter and an independent 25-tile patch (reaching 8 machines and 200 tiles total).
• High-Tier Materials: From Tier V onward, upgrades require Pig Bristles instead of Leather, along with accumulated Mud.

Myco-Composter Batches (Base: 12 Hours)

Each machine runs any of the three available recipes. Standard batch time is 12 hours:

Excavation Tools

• Digging uses standard Sand Shovels and Sand Drills.
• Key difference from Desert: Caves have NO daily dig cap. Dig as many patches as your tool supply allows.
• Cave patches do not contain prior chapter artifacts.
• Cave Skill Tier 2 boosts purchasable stock of Shovels & Drills in the shop by +50% / +100% / +200%.

Beetles: Rarity & Direct Feeding

All 4 beetle types are tradable on the P2P market and available from Cave Tier I:

• Brown Beetle: 80 XP direct animal feed.
• Blue Beetle: 160 XP direct animal feed.
• Pink Beetle: 320 XP direct animal feed.
• Amber Beetle: 640 XP direct animal feed.

Direct feeding note: Beetles can be fed directly to Pigs, Cows, Sheep, or Chickens.

Step 3: Pig Husbandry, Truffles, and Pig Bristles

Pigs introduce a full lifecycle with level-up milestones, nutrition preferences, and dual resource yields.

Pigpen Capacity & Rules

• Housing Capacity: 3 / 6 / 9 pigs based on Pigpen tier.
• Purchase Cost: 100 Coins per pig (first 3 starting pigs are free).
• Max Level: Any pig can reach Level 15 from Pigpen Level 1, following Cow XP progression curves.
• Target Farm Size: Midrange farms aim to maintain 6 to 9 synchronized pigs through levels 0 to 8. Higher levels require significant feed stockpiling.

Pig Feeding

Pigs accept all eligible crops at any level with preferred-band efficiency. Crop weight follows the formula: Weight = √(Seed Coin Cost × Base Grow Time in Minutes).

• Tier Anchors: 10 Carrots / 3 Cauliflower / 1 Wheat.
• Regular fish classify according to their standard fishing categories.

Mud Upkeep: Protection & +25% Final XP

• Applying 10 Mud to a pig grants 3 feeding charges.
• Each charge yields +25% final feeding XP (including direct Beetle feedings).
• Charges persist across sleep cycles.
• While charges remain, pigs are immune to sickness (does not cure an already sick pig).

Truffle Production

Truffles are collected every 24-hour sleep cycle starting at Level 1 and are fully tradable:

A farm with 6 mature pigs generates 24 Truffles per day before extra bonuses.

Pig Bristles

Bristles are NOT collected through daily sleep; they are awarded solely upon trading-in / retiring pigs at the Pigpen or completing Bounty tasks:

• Sickness Penalty: Sick pigs suffer a -25% penalty on awarded Bristles.
• Bristles are tradable and essential for high-tier Cave expansions (Tier V–VIII) and Weather protection crafts.

Step 4: Dynamic Global Weather and Hazard Mitigation

Season 16 features one active global weather event at all times:

• Continuous Cycle: 9 global weather events, lasting 3 to 4 days each (~27 to 36 days total cycle).
• Weather Forecast: Upcoming events are previewed 72 hours in advance.
• Overlays: Full Moon and Double Delivery continue as separate 24-hour overlays.

Weather Events & Magnitudes

Weather Protection Recipes

• Thermal Stone, Merino Wool Insulation, Shade Cloth: Each requires 25 Pig Bristles + 10 Merino Wool.
• Sandbag & Balk: Each requires 2 Leather.
• Wildflower Lure: Consumes 1 Flower (lasts 1 to 5 days based on flower tier). Adds +125% to +150% Honey (+187.5% to +225% during Blessed conditions).

Step 5: Advanced Cooking, Truffle Seasoning, and Cave Merchant

Truffles unlock high-XP gourmet kitchen meals and animal cycle acceleration treats:

New Cooking Recipes

Truffle Seasoning (Spice Rack / Aging Shed)

• Crafted in batches of 5 units per 1 hour.
• Effect: Grants -50% wake/sleep time across ALL four animal types (Pigs, Cows, Sheep, Chickens).
• Duration: 1 sleep cycle (2 with Vibraphone).

Goblin Cave Merchant

• Unlocked starting at Cave Tier I.
• Features 1 exclusive offer at Tier I, adding +1 offer per cave tier unlocked.
• Visits occur for 48 hours with advance announcements and per-player quotas.
