≈ 6 hSuggested range3 h 30 min – 9 h 45 minExperienced
≈ 4 h 15 minSuggested range2 h 30 min – 6 h 45 minBased on one person building the set for the first time, following the original instructions and using numbered bags where supplied. Includes normal piece-finding and minor adjustments; excludes long breaks, filming, dismantling and modifications. Sources may use different methods. This range is neither a statistical interval nor a limit: your build may take less or more time.
How we estimate times · sources and method
Editorial assessment of the first illustrated arrangement: A koala family gathers on a buildable tree with leaves and flowers at its base. Leaves of different shapes surround the koalas and add small modules to the trunk. A first build following the instructions, including normal piece finding; an adult may help when needed. Breaks and subsequent play are excluded. No verified timed build: indicative values with substantial variation.
Sources do not always specify the builder’s experience. The three experience bands are our editorial assessment, based on the complexity of the set and individual accounts where available.

The stories, places and inventions behind your build.
A tree-dwelling marsupial
The koala is a tree-dwelling marsupial rather than a small bear.
Read the full story
Koalas are tree-dwelling marsupials whose young spend about six months in the pouch before riding on the mother’s back. Victorian koalas have longer, thicker fur than Queensland animals, adapting to colder conditions. The informal bear nickname conceals a different biology.
A particular menu
Its diet consists almost entirely of eucalyptus leaves, with preferences for particular species.
Read the full story
Eucalyptus leaves supply almost the entire diet, with preferences among tree species. Victoria lists manna, swamp, blue and river red gums among local food trees. The low-energy diet helps explain long daily inactivity, making energy conservation part of the animal’s lifestyle.

Kiki’s music connects everyday city life with the pleasure of flight. It accompanies small inhabited settings and imagined movement as an editorial pairing across different worlds.
