Dynamic cinematic video scene, official portrait style, Groot as a substitute teacher in a classroom, camera slowly panning across as he writes "I am Groot" repeatedly on the blackboard in chalk. His arm moves rhythmically, chalk dust floating in the air with soft light rays shining through classroom windows. Subtle motion blur on his writing hand, the camera shifts from over-the-shoulder view to wide shot of the whole classroom, blackboard filling with "I am Groot" lines, creating a looping, animated, official yet humorous atmosphere.
