Purpose: This paper aims to examine unexpected arrivals of adult-oriented digital media in the playful storied environments of Grades 1 and 2 classrooms and the possibilities such unsettling literacies may offer. Design/methodology/approach: Posthuman perspectives provide this study's theoretical grounding and methodological approach. Actor-network-theory and thinking with theory are used to examine school play with two video games and the literacies entangled in children's same game machinima productions. Findings: Explorations of transmediascapes animate entangled meaning-making practices across virtual and material childhood spaces. They provide openings for educators to understand their students' literate world-making and consider how those unsettling literacies might have a place in the classroom as generative rather than to-be-avoided contaminations. Originality/value: The theoretical and methodological engagements of this paper offer opportunities to re-consider unsettling literacy encounters as generative contaminations rather than noxious intrusions. This paper shows how, in engaging with unsettling literacies, educators may participate with children in meaningful literacy practices responding to both the tantalizing and the troubling aspects of particular transmedia.
