Accomplished LEGO artist Ted Andes has presented us with a cute riddle: What’s under twenty pieces, adorable and could potentially demolish your house? Baby’s First Bulldozer. This is a prime example of minimal part use for the win. Also known as the Pamper Pusher, this little guy was built as a part of a collaborative effort for Brickworld Chicago. I always enjoy seeing simple two- or three-piece combinations that just work. The tread system made of the microfighter wheel base, a 1×3 thin Technic lift arm, and a stretched tyre, is absolutely one of those.
