Once you make a character, you can add them to this studio! https://scratch.mit.edu/studios/25079938/ ways to makeing them are in credits click and hold to drag around and space for the other powerpuff (this one but in a different pose.)
Want to make your own Powerpuff characters? You can remix this project https://scratch.mit.edu/projects/323395688 and use the sprites! thank you for this project https://scratch.mit.edu/users/Scratchteam (don't know how to properly @.)
