In Google’s implementation, when you react to a message with certain emojis, you’ll see colorful animations that burst on the screen and highlight the message you are reacting to — such as floating exclamation marks, flames, inflatable tube men, an umbrella, etc. These reactions are currently limited to a select few emojis, but hopefully Google expands the list in the future. You can see an example of how these animations work when reacting using emoji in the video below:

As Google continues to add new features to Messages, the app is becoming increasingly more feature-rich and user-friendly. The addition of animated emoji reactions is a welcome addition that adds a bit more fun and personality to your conversations.
