Legs

On Roblox, your character, or Humanoid, has two legs which hold you up from the ground and can make you jump. They are 1 stud wide, 1 stud long, and 2 studs high. Legs are below the torso. Even if your legs are deleted, you can still walk, and in certain cases, you may/may not be able to jump. If only one leg is removed, you can still jump.

Trivia

 * Getting rid of your legs makes you more prone to death, especially on lava platforms that dissolve your body parts. This is because your legs hold up your torso, and when your torso is destroyed, you die.
