Save the maze picture in this step to your computer and upload it into Scratch as a new sprite. Once it appears, drag it into the centre of the stage area.

If you cannot upload the maze image as a sprite, you can use the starter project here.

Scratch: How to upload a sprite

You can upload images and sprite files into your project. To upload a sprite follow these steps:

1. First save the image or sprite file onto your computer. You do this by right clicking on the image or link and then selecting 'Save image/link as...'.
2. Choose a location on your computer such as your desktop and save the file.
3. In your Scratch project, put your mouse over the Choose a Sprite button.
4. Click on the 'Upload Sprite' button.
5. Go to the folder you saved your file.
6. Select the file and click 'Open'.

The new sprite will upload into your project and appear in the stage area.

Add the beetle
Add the 'Beetle' sprite from the sprite library. Drag the beetle to the start of the maze (the gap at the left of the maze).

Shrink the beetle
As the beetle sprite is too large to fit in the corridors of the maze, we'll need to add the following code to the beetle to shrink it:

Position and point the beetle
Once you have added this code, click the green flag to shrink your beetle and then drag it to the start of the maze (near the bottom left of the maze). Now add the following code to your existing code block so that the beetle always starts in this location and is pointed in the right direction.

Scratch: How to add a sprite from the library

To add a sprite from the sprite library follow these steps:

1. Put your mouse over the Choose a Sprite button
2. Click on the magnifying glass
3. Find the sprite you want in the library
4. Click on your chosen sprite

You can use search box or the filter links (Animals, People, Fantasy etc) to locate your sprite.

We need something at the exit of the maze that we can detect when our beetle sprite gets there, so we're going to add a small green circle by editing the maze. 

Click on the maze sprite in the sprite list below the stage area and then click on the 'Costumes' tab, this will open the sprite editor. To add a green circle follow these steps:

1. Click 'Convert to Vector'
2. Click the 'Circle' tool
3. Choose a green colour
4. Turn off the outline
5. At the exit of the maze draw a circle by:
   
6. - holding down the Shift button
   - and holding down the left click button
   - and dragging across to draw a circle
7. Drag the circle to the exit of the maze

If you make a mistake just click the back button (a rounded arrow pointing left).

We're going to create and use a 'steps' variable for the amount of steps the beetle will take each time it moves. Create a new variable called 'steps' and add the following code:

In the Variables palette, create a new variable by clicking the 'Make a Variable' button.

Once you click this button a box will appear asking what you want to call your variable. Give it a name that reminds you what you will be using it for. For example, if you wanted to keep track of your score in a game, you would create a variable called 'score'.
