3-4 hours for kids with basic scratch experience
Let's revise the concepts we have learned so far.
Stage – An area where you can see the output of the project and how it’s running by clicking on the green flag above it. You can stop running your project by clicking on the red button.

Script area – This is the place where you will have all your instructions and your blogs placed. Scratch provides different script areas for each sprite and the background section.
Block Pallet – It contains nine categories of blocks that can be used to code for the project in the script area. All you need to do is drag the required block and drop it on the script area.
Background selection – You can either upload an image stored on your device or select the background from the Scratch gallery or opt for painting your own background or get a random surprise background by clicking on the surprise option. All you need to do is to hover your mouse over the icon as shown below and choose the appropriate option.
Choose the sprite – Sprites are nothing but the characters that you want in your project. You can choose the sprites in the same way you select a background. You get four options here: uploading from your device, getting a random surprise sprite, painting your sprite, and choosing the sprite from the gallery, as shown in the image below. The process of selection remains the same as that of background selection. Hover your mouse over the icon and choose the appropriate option. You can have more than one to any number of sprites you require on stage.
Sprite properties – Here, you can look at and modify the name of the sprite, the x and y coordinates or position of the sprite, whether it is shown or hidden on stage, the size of the sprite, and its direction of it. The section is located right above where you see all the sprites you have added to your project
Costumes of sprites – A single sprite in Scratch can have multiple costumes which can have the same sprite in different postures, in different colors, etc. You can navigate to have a look at the selected sprite’s costumes in the costumes section shown below.
For this project, please look at the code here if you are stuck:
