The second series, which is again aimed at four- to five-year-olds, comprised five episodes, focusing on the four basic two-dimensional shapes; each episode would open with Lolita standing by a mobile with the four basic shapes hanging from it and singing the series' main theme, "Squares and Triangles, Circles and Rectangles" as the mobile began to turn. Once it had stopped turning, she would walk over to the shape that was nearest to her, then ask the viewers if they knew what it was, before it lit up and she told them - and from this series onwards, El Nombre was given "two" sketches per episode (the first to show Juan instances of that week's shape around the town, with Juan being clumsy and getting confronted by the other villagers after El Nombre had left, and the second to draw it in the desert sand). This series also featured four cut-out animated characters made up from the shapes its episodes were focusing on (a circular man with magical powers, a square robot with transformation powers, a triangular knight with a magical lance and a rectangular man); in the last episode, they worked together to build a house (after the rectangular man built one entirely out of rectangles, and the square robot, triangular knight and circular man transformed them into their own shapes). Each episode would end with Lolita singing an "extended" version of a song that had been heard earlier in the episode during a montage of the shape around the real world (for the last one, she continued over the credits) and setting viewers the challenge of seeing how many of that week's shape they could find before the next episode.
