LEGO QUATRO was a theme that used specialized QUATRO blocks which were larger than DUPLO bricks. The theme was released in 2004 and was designed for pre-school children and babies ages 1 to 3 and was discontinued in 2006. The name QUATRO comes from the fact that the bricks were quadruple the dimensions of the traditional LEGO System bricks. The logo of QUATRO is an elephant which is the same as the old logo of Primo.
