The puppet consists of a humanoid skeleton and pieces attached to it. You can make your own characters by linking custom pieces to the puppet's skeleton and adjusting the proportions.
Use the timeline to animate the puppet.
To unlock the puppet for customization, highlight a blue sphere on top until you see an icon with a lock to appear. Press it to unlock the puppet. After you unlocked the puppet, you can freely move out any body parts, delete them and link new parts to bones and other parts.
All the characters in the videos below were made using the puppet.
