Will Eucalyptus speed bamboo the way Panda does?

No. Panda’s Bamboo Boost targets bamboo crop value. Koala’s Eucalyptus is limited to tree-category growth in the roster text.

Why does age 25 weigh exactly 7 kg on a default Koala?

Because (2.2 ÷ 11) × (25 + 10) = 0.2 × 35 = 7. Same hatch at age 50 is 12 kg. Use those checkpoints when a listing’s weight looks off for the stated age.

Grow a Garden Koala

Koala is the rare that makes tree-category tiles feel worth the long timer — Eucalyptus is written as bonus growth on that crop family, not as a bamboo or vegetable generalist.

Koala weight progression

Koala hatches at 2.2 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.

Koala weight by age
Age	Projected weight
Age 1	2.20 kg
Age 25	7.00 kg
Age 50	12.00 kg
Age 75	17.00 kg
Age 100	22.00 kg
Age 125	27.00 kg

Playstyle

Cluster tree-tagged crops and keep Koala centered on that grove. Editorial tier B rare fits a strong niche with a clear category lock: empty the slot if your garden is mostly flowers or water. Red Panda Climb helps elevated harvest speed on a different axis; Panda Bamboo Boost owns bamboo value and does not share Eucalyptus’s tree wording. Worm Aerate nudges soil quality globally and can sit beside Koala without claiming the same bonus.

Weight & trading

Hatch 2.2 kg produces unusually clean checkpoints: age 25 is exactly 7 kg, age 40 is 10 kg, age 50 is 12 kg, and age 100 is 22 kg under (2.2 / 11) × (age + 10). Those round numbers make Koala easy to sanity-check against the weight calculator when verifying a listing.

Eucalyptus: bonus growth on tree-category crops. The roster does not publish a percent, aura radius, or sell-value rider beyond growth bonus. Category membership follows each crop’s tags — if a bush is not tree-category in the crop database, do not assume Eucalyptus applies. Bamboo remains Panda’s lane per that species’ ability text.

Koala in Grow a Garden

Grove layout beats scattered trees

One Koala covering a tight tree block usually outperforms the same pet watching three lonely oaks on opposite corners. Rebuild the grove if tree tiles were planted as decoration rather than as a production wing.

Sloth Slow Growth stretches timers for bigger yields on many crops; Eucalyptus speeds tree-category growth specifically. They can coexist on different plots, but stacking both on one tile type needs a clear goal — speed versus extended yield — rather than automatic double-slotting.

Reading tier B as niche strength

Editorial tier B does not mean Koala is weaker than every tier A rare; it means the ability is category-gated. On a tree monoculture, Eucalyptus can matter more than a higher-tier pet that never touches trees.

Trade conversations should separate rare rarity, tier B ranking, and whatever ask the buyer can afford. Heavy age on a 2.2 kg hatch is attractive for weight screenshots, but buyers without tree plots will pass regardless of kilograms.
