If you've got a big bin full of miscellaneous LEGO pieces, you can probably build the models in these fun, well-illustrated idea books, many of which use fewer than 100 bricks.

These mechanical characters have got oodles of personality. With names like Budd EE (a gentle giant with a big smile), Gizmo (with orange pigtails and a talent for tech solutions), Tin Byte (who looks a bit like a flying Tin Woodsman), Feeder (with an oven in his middle), and Amah (who can comfort little robots in her lap), they are ready to clomp, roll, and wing their way into your LEGO play.
