In this add-on, you'll program a hidden surprise on your profile page.

This video won't tell you exactly what your surprise should do but it will give you some ideas for how to program it.

In this example, the hidden surprise code is for the Icon sprite in the top right corner of your profile page.

When you click on the Costumes tab for this sprite, you'll see some preloaded costumes that you can use.

The Switch Costume To blocks will change the Android to a specific costume.

This example also has the sprite repeat changing its size and costume.

The repeat loops are found on the Control menu.

The Change Size blocks are found in the Looks menu.

Try out other blocks from the Motion and Looks menu to move the sprite across the page and reset your project at the end using the Go To, Switch Costume, and Set Size To blocks.

Now it's your turn.

Choose a sprite that will have the hidden surprise code.

Use different blocks from the Motion menu to move the sprite, the Looks menu to change the sprite's costume or appearance, and the Control menu to make the sprite repeat an action.

To reset the sprite so that it goes back to its original costume, size, and location, use a Switch Costume and Set Size To blocks from the Looks menu and a Go To block from the Motion menu.
