Turtle Shape Editor
Now that you have your turtles moving, you are ready to learn how to change the shape, size and color of your turtles. Let's start by creating a new turtle shape. Select **Tools** -> **Turtle Shapes Editor** -> **New**. Create a new shape with the tools provided and give your shape a //name//, then select **OK**. You can also find many shapes to use by selecting **Import from Librar****y**.

Setting the shape or any other attribute of a turtle is a //**turtle**// function. So try out the following code in the **Command Center**, substituting the name of your newly created shape where you see //myshape//. Remember crt is an //**observer**// command and the rest are //**turtle**// commands.

set shape "//myshape//" set color white set size 3

Create buttons
Now that you've learned so many different commands, an easy way to reuse those commands without having to type them in all the time in the **Command Center** is by creating a button. To create a button, you select the **+Add** and then click somewhere in the white space below. A button dialog box should appear. Type the following //**Observe**////**r**// commands into your button and give it a **Display name** of setup then select OK.

Click on your new **setup** button. Did 10 turtles just get created? Now try creating a button to change the shape, color and size of your turtles. Remember, these are //**Turtle**// commands.
