Increasing numbers of children are caught up in global flows of moving peoples. This movement may be voluntary or forced and is experienced within a range of settings. Coming from diverse linguistic and cultural backgrounds, and moving around the world due to their parents' employment, the children found in traditional International Schools are a case in point. This paper focuses on the experiences of two sisters in the first year of their family's global relocation. In the midst of change, the digital world Club Penguin™ offered these two globally mobile children a familiar and welcome site of continuity and belonging. This exploration of the role of digital worlds and digital literacies in these girls' experience contributes to an understanding of connections between global movement and digital literacy practices. Greater awareness of the significance of digital literacies in globally mobile children's lives provides fresh insights into how children participate in digital spaces and has implications for literacy educators supporting young people in contemporary times.
