Click the Stop Sign to 'pause' the logo on the one you want. Then you can change the Backdrop, and use it for anything! "Create your own Google logo" is an activity where you can use your creativity and imagination to bring the Google logo to life using code. Make the letters dance, tell a story or create a game. Try it out at g.co/csfirst/logo Once you've created your logo, you can add it to the studio: https://scratch.mit.edu/studios/4466845/
The worse than horrible coding was by me. The cute little characters that make the google sign was by CSFirst though. (He also designed all the backdrops) I just added the coding and Backdrop button.
