TIME TO BUILD
How long does it take to build Sulley, Mike and Boo Figures?
A starting point for planning your build. Times for each experience level are editorial estimates, not measurements submitted by HowLongToBuild users.
Editorial estimate · first build
Intermediate
≈ 1 h 15 minSuggested range45 min – 2 hExperienced
≈ 45 minSuggested range30 min – 1 h 30 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: Sulley, Mike and Boo from Monsters, Inc. are recreated as small BrickHeadz figures. The figures are assembled individually: the estimate covers the complete trio. 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.
