The Bully Caterpillar (2020)

Harold was a bully caterpillar. He was the biggest caterpillar around and could do whatever he wanted. Then, one day, a beautiful butterfly stopped to see him. Unbeknownst to Harold, the butterfly was his mother. The butterfly shows him how to love and he makes a cocoon and stays inside to think about the new person he wants to be. In the meantime, he saves the life of Stealth, a very large blackbird who wanted to eat him. Lord Mongus won't let the caterpillars in the dark forest change, so their purple stripes have changed to yellow, as they are afraid to stand up to him. Once Harold emerges from his cocoon, Nada comes to him because she is in trouble with Lord Mongus. Harold goes to see Lord Mongus and gets trounced. He flies back to Nada with ripped wings. She fixes his wings with her "cocoon making stuff". Harold gets the other caterpillars together to overthrow Lord Mongus, while Nada changes. Nada changes to Llena (complete) and they live happily ever after.
