Click the Green flag and dispatch the Gobo army to fix the server. Remix if you like and edit it! You can change the music, change the character that'll have an army of clones dispatched etc. I don't know whether Turbo Mode (shift+click green flag) or normal playback work better.
Scratch had a bit of an error a minute ago, and it gave me an idea! I made it into a simple loop animation! Credit to MIT for the inspirational error screen. Updated it so that they spread out a bit more.
