Blockoland is a large theme park made almost entirely out of "Blocko" building blocks. The Simpson family visited the park on a day out. Blockoland is divided into three parks: Rectangle Land, Cube Country, and Squaresville.
Behind the Laughter[]
Blockoland is a parody of Legoland, a chain of amusement parks based on the Danish toy brand Lego. There is a Blockoland in Springfield and in Denmark; the latter is the birthplace and headquarters of the Lego Group.
Legoland has also been shown in more than one Simpsons episode.
