1x10 - My Little Pony: Equestria Girls - Summertime Shorts

In art class at Canterlot High School, Pinkie Pie can't think of anything to paint. Sunset Shimmer tells her to find some inspiration and get her "creative juices flowing". Taking her advice literally, Pinkie gets a juice drink from Granny Smith in the cafeteria, but she still doesn't have any ideas. Next, she tries to find inspiration in nature by interacting with birds in the trees, but still nothing. Lastly, she tries finding inspiration by playing her drums. As she really gets into her drum solo, she taps her drumsticks on everything from the music room back to the art room, but still no inspiration strikes her.
