Sulley, Mike & Boo (LEGO 40861)

About this set

This LEGO BrickHeadz set, number 40861, packs 303 pieces at a 3/5 difficulty and builds three characters from Monsters, Inc.: Sulley, Mike and Boo. Each figure uses the familiar big-head, block-body BrickHeadz ratio and sits on its own black base plate, so you can line them up or split them across a shelf. The palette leans on blue-green, purple, beige and black; Sulley's fur is layered from sloped bricks, Mike's green body contrasts with his purple spots, and Boo picks up the beige and purple accents. Mike's eyes are printed elements, which saves the fiddliest sticker work, and Sulley has round studs on the sides of his body, so keep the left and right mirrored when you attach the arms. The heads are built from many small pieces, so sorting by color first will speed up the clutch-heavy sections. With 303 pieces across three figures, each one is a quick build. Start with Mike if you want the simplest structure, then move to Boo and Sulley; this suits builders who have done a basic BrickHeadz before and want a character trio rather than a single display piece.
