This episode is about a young rhinoceros who struggles with managing his anger. The story follows Rumble through a difficult day where he gets frustrated with his little sister Pearl's constant copying and later during a soccer game incident. His mother teaches him to identify the feelings beneath his anger using the metaphor of lightning (the underlying emotion) coming before thunder (the anger). Using the biblical verse from Ephesians 4:26 as guidance, Rumble learns that when he feels annoyed, suffocated, or overwhelmed, he can express these feelings with words instead of outbursts. Through practicing this emotional awareness, his relationships improve, especially with his sister Pearl and his friends like Ziggy the zebra. The story emphasizes that all feelings, including anger, are natural and can be managed in healthy ways with God's help.
