Creativity is an intrinsic human ability with multiple benefits across the lifespan. Despite its importance, societies not always are well equipped with contexts for creativity stimulation; as a consequence, a major decline in creative abilities occurs at the age of 7 years old. We investigated the effectiveness of using a robotic system named YOLO as an intervention tool to stimulate creativity in children. During the intervention, children used YOLO as a character for their stories and through the interaction with the robot, creative abilities were stimulated. Our study (n = 62) included 3 experimental conditions: i) YOLO displayed behaviors based on creativity techniques; ii) YOLO displayed behaviors based on creativity techniques plus social behaviors; iii) YOLO was turned off, not displaying any behaviors. We measured children's creative abilities at pre- and post-testing and their creative process through behavior analysis. Results showed that the interaction with YOLO contributed to higher creativity levels in children, specifically contributing to the generation of more original ideas during story creation. This study shows the potential of using social robots as tools to empower intrinsic human abilities, such as the ability to be creative. **Materials** We provide open-access to the following materials: - *Instructions and questionnaires.* We provide the verbal instructions used during pre-test, intervention, and post-test. Additionally, we provide whenever possible the questionnaires used during the study. - *Data base stories.* We transcribed and translated from Portuguese to English the stories created by children. They show the creative process of storutelling between children and the robot. - *Database.* We provide the database used to conduct the statistical analysis. The database document was prepared using IBM SPSS Statistics version 25.
