For this add-on, think back on the CS First experience.

What made you laugh?

For example, in one CS First club, everyone was obsessed with squirrels, bacon, cheese puffs, and unicorns.

It seemed that each project included at least one of these items.

For your project, think about something you and your friends laughed about.

What would you portray in your project?

Would you use a secret key, that when pressed, it would show and hide?

Maybe it would play a favorite sound that makes you giggle.

Maybe when you click a sprite, it switches costume.

Make something unique for your friend.

Now it's your turn.

Add an inside joke to your project using events, costume changes, and/or sounds.

Add instructions to your project so your friend knows how to see the inside joke.

Do they press a certain key, or click a sprite?
