(the instructions are here but it's from another project, the steps are:) step 1. tell your friend to choose a side or you choose, step 2. Tell him to share an assist so you can see and save the characters in your backpack so you can see what he's going to do or share an assist yourself and tell him to share the version without anything done. step 3. In the assist version project, save his creation to the backpack and put the version and the sound (and animation if you want) in your project, and then tell him to delete the assist and share the real version.
This project was created as; instead of waiting for your scratcher friend to arrive at your house, you invite him to make the version here. (if you also want to remix a project and show the table to your friends, that can also be done). doubles = 10 for each, group of 3 = 8 for each quartets = 5 for each. to make of 3; https://scratch.mit.edu/projects/1057705322
