In this story, you'll program an Easter egg that changes the appearance of a sprite in your story.

An Easter egg is a special feature or inside joke that computer scientists add to programs for users to find.

Some fun examples of Easter eggs include searching for do a barrel roll on Google, or doing a Google image search for Atari Breakout.

For this add-on, you'll add an Easter egg that changes the sprite's appearance when it's clicked.

To start, choose a sprite.

Click Events and drag out an event for your Easter egg.

This example we'll use when the sprite is clicked.

But you might choose a keypress event or something else.

Then, all that's left is to code it.

Try saying a message like, "Hey!

"You shouldn't have done that!"

Then, put a few different change effect and Motion blocks into a forever loop.

Try out different things until you come up with a fun Easter egg that will add a little mystery and excitement to your story.

Now it's your turn.

Add an event to trigger your Easter egg.

Put some change effect and Motion blocks into a forever loop.

And then once you've done these things, you should have your very own hidden Easter egg.

Show your program to friends and see if they can find the Easter egg your hid in your story.
