My DD3 is obsessed with telling long involved storied that always include a green t-rex, an orange t-rex, which is nicer, and the Disney princesses getting chased and eaten by one or the other t-rex.
The setting changes, the victim changes, and the heroine princess changes every time, but the rest are constants. I know a strange combination, but they are really funny stories with great plot lines. If I only had the camera to record her while she was telling them.
