Although the educational value of African oral traditions, particularly folktales, has been discussed widely in social studies of children, education and folklore, riddling is not commonly investigated as a part of children's everyday social practice. In this article, I present riddling as a part of children's expressive culture, through which they play together and learn about their local environment. I generated the data through ten months of ethnographic fieldwork among Guji people in southern Ethiopia. Based on analyses of the times and locations of this activity, as well as the social interaction involved, I argue that children perform riddling in order to entertain themselves and to learn from their immediate social and natural environment through discrete peer networks.
