What is the exact Rainbow Touch proc percentage?

The roster only says a small chance on harvest. No verified percentage is published in site pet data—avoid guides that invent fixed rates without citing a current tooltip.

Should Unicorn sit on one giant crop or many small ones?

Many harvest actions better match a per-harvest chance. Prefer rows you pick often; a single long-timer plant gives fewer rolls even if its base sell value is higher.

Unicorn drips rainbow chance into ordinary harvests: Rainbow Touch adds a small rainbow mutation chance on harvest, favoring volume picking over waiting on a single ultra-slow plant.

Unicorn weight progression

Unicorn hatches at 2.5 kg and grows with the formula W = (hatch ÷ 11) × (age + 10). The table below projects its weight at each age milestone so you can plan trade timing and weight targets.

Unicorn weight by age

Age 1	2.50 kg
Age 25	7.95 kg
Age 50	13.64 kg

Playstyle

Park Unicorn on high-frequency harvest rows—multi-pick bushes, fast regenerating crops, or any layout that generates many harvest actions per session. Each harvest is another independent roll at the small chance described in the ability text. Divine Prismatic Butterfly and legendary Kitsune cover rainbow-adjacent or enchanted/mystic lanes with different wording; Unicorn remains the harvest-proc legendary on editorial A. Legendary rarity does not imply S-tier editorial rank or a fixed trade quote.

Weight & trading

Hatch 2.5 kg sits exactly on the Large hatch threshold. Weight checkpoints: age 25 ≈ (2.5 ÷ 11) × 35 ≈ 7.95 kg; age 50 ≈ 13.64 kg; age 75 ≈ 19.32 kg; age 100 = 25 kg. Large classification plus clean 25 kg cap make Unicorn easy to audit in trade windows.

Rainbow Touch grants a small rainbow mutation chance on harvest. Rainbow is a growth-category tag at ×50 in the mutation catalog when it lands. No numeric base rate, age curve for the chance, or AFK/auto-harvest rule appears in pets.ts—call the chance small as written and verify harvest triggers in your client.

Volume harvests beat single rolls

Because the chance is small, expected rainbow tags scale with harvest count more than with any single crop’s base value. A slow pumpkin harvested once contributes one roll; a busy berry row may contribute dozens.

That does not make Unicorn a replacement for guaranteed mutation applicators. It is a probabilistic rainbow sprinkle on top of whatever else your garden already does.

Rainbow lane without inventing rates

Prismatic Butterfly Spectrum language targets rainbow and prismatic on flowers; Unicorn rolls rainbow on harvest actions generally. Choose by crop category and how you harvest, not by which name sounds grander.

Editorial A and legendary rarity are not market appraisals. Age and proven rainbow icons on harvest logs matter more than hatch prestige when discussing offers—and this page still will not invent Sheckle prices.
