Indonesian Third Culture Kids (TCK) in their late teens aged 17–19 often experience emotional pressure during repatriation, which is the process of returning to their home country after growing up abroad. They frequently feel lonely with a lack of stable support systems, and having been exposed to foreign cultures that shaped a diverse worldview compared to non-TCK peers, often prevents them from creating a stable group of friends. To address these challenges, the author designed a short animated series with therapeutic effects based on conventional Art as Therapy theory. This short animation aims to help Indonesian TCKs manage their emotions and build a sense of belonging with both fellow TCKs and non-TCK individuals. The short animation is based on Developmental Animation, combining orthodox and experimental animation theories through an Art as Therapy lens. The research started from collecting real-life experiences from repatriated Indonesian TCKs, as well as experts in art therapy and art psychology, supported by literature studies on TCK identity and animation theory. The developmental animation features visual elements inspired by traditional art tools and organic textures commonly found in Art as Therapy workshops. The storyline follows two main characters as they face various common repatriation challenges, serving as a reflection of real experiences. Each episode runs for 2–3 minutes and is designed to offer calmness and emotional support. This project helps Indonesian TCKs feel more understood, less alone, and better prepared to face repatriation in Indonesia.
