Claudio's eyes were light blue, as opposed to the rest of his family's brown eyes. In fact, none of his ancestors have light blue eyes. He is one of three deceased Veronaville Sims to have a pre-made biography (the other two being Contessa Capp and his wife Olivia Monty) and the only one as well to already have a career and skill points. Claudio also has personality points, as many deceased Veronaville Sims do not. He, his wife, and Contessa Capp can be resurrected using the Resurrect-O-Nomitron and will look just like they appear in their head-shots but the player will have to restore their marriages. He even holds a job as a Sous Chef to the family restaurant, despite not having the skills for that career level. Patrizio's memories might suggest Claudio and Antonio are twins, though that is never stated. Claudio and his wife both died due to starvation.
If SimPE is used, a hidden thumbnail of Claudio as an elder can be accessed. Although his facial features will be the same, he has a different outfit and grey hair. The reason for the thumbnail existing is unknown. In Claudio's character files, he has a hidden Knowledgeaspiration token. According to his age data, he was 23 days from being an elder when he died. Even though Claudio had reached level 6 of the Culinary career, he doesn't have the corresponding career reward available for him to purchase.
