Add yourself into the running animation. Then watch your creation run from the ghoul! Meters Ran is slightly bugged.
Simple. For the ghoul: Offscreen: set ghoul offscreen and put a Go To x y script after the When Flag Clicked block. Then make him move 15 steps onto stage with 0.1 second in between steps. Then forever repeat 4 steps forward wait 0.1 seconds repeat -4 steps forwards wait 0.1 second. Same thing for the running characters except place them on screen. The beatbox is like the ghoul expect it emits music ( any kind! ) to make it more entertaining to watch the characters run!
