This is another project I made in a school Computer lesson (don't worry, I'm not skipping one of the best classes - this was the task). Scratch Cat will ask you what five things you want to add to your shopping list, and once you've told him, he will write them down for you.
If you wanna use this for an actual shopping list, maybe use Turbowarp so you can pause it: https://turbowarp.org/912884783
