In the installment, Homer wakes up in a world where his family and everyone in Springfield are made of Legos. He must then try to "put together" how he got there and somehow figure out how to get home before he is stuck in a world of bricks forever.

Meanwhile, Fox's long-running animated series returns with two new episodes airing back-to-back March 9 from 7:30-8:30 p.m.
