The starter project has three costumes for the happy, sad, and angry expressions.

In this Add-On, you'll further animate your monster to show another emotion.

Think of other emotions your monster might feel like surprise, fear, or excitement.

To start, right-click on the calm costume, then click duplicate.

This creates an exact copy of the calm emotion costume.

Modify the new costume to create a new emotional expression.

This example creates a surprised expression.

Use the reshape tool to change the way your monster looks.

Feel free to create your own features, such as eyebrows and animated cartoon effects to customize your monster.

If you don't like a change you made, use the undo button to remove it.

The vector edit tools in Scratch allow you to easily manipulate the costumes and features of the sprite, like the animators do when they create animations.

Currently, the costume names are calm2, calm3, calm4, and calm5.

Rename each costume to fit your animation description.

The example uses surprise1, surprise2, surprise3, and surprise4.

If you add more than three costumes for one animation, code your project to go to a fourth or fifth costume.

Go back to this code tab.

Duplicate the wait and switch costume to join feeling blocks and add them under the previous switch costume block.

Change the number in the second value of the joined block to four to make the monster switch to the fourth costume.

Follow these steps for every additional costume you create.

Be sure the name of the new costume matches the number in the join block exactly.

If it doesn't, it may create bugs in your code.

Finally, add a show feelings block to further animate your monster.

This example, for surprise, says, "When I got home, my friend bought me more ice cream."

Test your animation.


Now it's your turn.

Duplicate the monster costumes to further animate each emotional expression.

Use the vector animation tools to animate your monster to show another emotion.

Then, add a new show feelings block to incorporate the new expression.
