Press Space for next costume. WASD to move the thing.
To get the plugin, see inside, and put the "3D (Left/Right) (Up/Down)" custom block in your backpack. Plug it into a project on "When green flag clicked" and it will work (It's on a forever loop already) How to use: Left/Right and Up/Down determine which way the 3D effect goes. In Left/Right (String #1) type "Left" for left and "Right" for left. In Up/Down, (String #2) type "Up" for up and "Down" for down. CASE SENSITIVE! FIRST LETTER MUST BE CAPITAL.
