How do you coordinate interactions between sprites in animations? Explore two different strategies for synchronizing interactions between sprites -- timing and broadcasting -- by remixing a joke project.

Observe how the author animated the conversation between Penguin and Nano using wait blocks. Remix the Penguin Joke project to use the broadcast and when I receive blocks (instead of using wait blocks).
