Sometimes your fears are all in your head.
It's true sometimes your fears are all in your head and Badou learned that when trying to get over his stage fright. He thought that if he performed, then everyone would laugh him but he discovered that Jake and his friends were laughing about the history lesson they had.
Things are less frightening when done with friends or family.
Badou wasn't the only one to learn this lesson, so did Babar the reason why didn't want to dance with Celeste is because he wasn't very good and he too had a fear of looking silly with that in mind both he and his grandfather both got over their stage fright despite being silly but with everyone laughing with them.
