The placing of the cat on to the backdrop is controlled by coordinates on a scale from -200 to 200. The x-axis controls movement left to right and y-axis up and down. If you move the cat in the Display area the coordinates will change in the Sprites area.
Choose the starting position of the cat by placing it somewhere on the backdrop. In this case on the boardwalk.
Using the appropriate block in the Motion library you can choose the starting point of the sprite. In this case the starting point is where we placed the cat.
You can change costumes on the cat making the impression of the cat walking.
Go to the looks library and make changes to your program making it look like this:
If you want the cat to be another size you can change that in the Sprite area.
Now test your program by pressing the green flag above the Display area. Let the pupils play around with the different settings making the Sprite move in different ways or changing the backdrop.
