Tico is Rigodon's companion and former circus partner, initially joining the journey concealed within Rigodon's luggage without Willy Fog's knowledge. His background includes performing alongside Rigodon in circus acts before seeking stable employment, leading to their inseparable partnership during the global expedition.

Physically, Tico is a small, hamster-like creature consistently wearing red dungarees. His design emphasizes diminutive stature, often contrasting with his substantial appetite, a recurring trait highlighted across episodes. The character's original Spanish version features an Andalusian accent, though adaptations alter this, such as an Italian identity in English dubs or a Mexican persona in Latin American releases, complete with region-specific exclamations.

Tico provides comic relief through exaggerated hunger, frequent meal reminders, and moments of cowardice. Despite this role, he demonstrates loyalty and situational courage, particularly when aiding Rigodon or confronting threats to friends. Instances include participating in fights despite visible fear and assisting in key narrative moments like Princess Romy's rescue. His central relationship with Rigodon is characterized as hetero life-partners, built on shared history and mutual devotion.

A significant artifact tied to Tico is an ancient Egyptian "sun-clock," acquired early in the journey. He consults this device repeatedly to track time, integrating it into plot developments related to scheduling challenges. While often requiring rescue or generating mishaps, his actions extend beyond mere nuisance; examples include clarifying misunderstandings with indigenous groups and supporting allies during crises.
