Hijitus lives inside the Manuel Garcia Ferre universe shared with many other characters like Anteojito, Larguirucho, and others.

For Argentine popular culture "living inside a pipe" is analogous to being poor, so this means that Hijitus economic situation is bad.

When things became hard (usually the situation has reached a dramatic level) he transforms into Super Hijitus and acts to defeat Neurus and other villains.

A recurrent theme was Neurus and his henchmen Pucho and Serrucho trying to separate Hijitus from his hat or steal it for possessing his magical powers, only to end up failing and in jail.

The first animated appearance of the character, named Las Aventuras de Hijitus, made its debut on TV in 1967.
