The animation is about a young wolf finding a butterfly. His mother scolds him and warns him of the Butterfly Effect. Ten years later, he is very thin and dull after leaving the pack, but finds another butterfly. It reminds him of when he was young, and he is cheerful again. The moral is that no matter what happens, try to be happy again.
Thank you Scratch for the music, it was absolutely perfect for what the wolf was going through!
