How do i animate threw network

Im trying to learn network so im working on a project to get better at it. All I need is this script converted to network so I can understand it.

heres the script

 public GameObject head;
 public Animation walk;
 public int speed = 1; 
 public GameObject MouthOpen;
 public GameObject MouthClosed;
 public GameObject eyeLids;
 
 void Start()
 {
     MouthClosed.active = false;
     eyeLids.active = false;
 }
 
 void Update()
 {
     if(Input.GetKeyDown(KeyCode.T))
     {
         MouthOpen.active = true;
         MouthClosed.active = false;
     }
 
     if(Input.GetKeyUp(KeyCode.T))
     {
             MouthOpen.active = false;
             MouthClosed.active = true;
     }
     
         if(Input.GetKeyDown(KeyCode.B))
         {
             eyeLids.active = true;
         }
         
         if(Input.GetKeyUp(KeyCode.B))
         {
             eyeLids.active = false;
         }
         
 
     if(Input.GetKey(KeyCode.W))
     {
         animation.Play("Walk", PlayMode.StopAll);
         animation["Walk"].speed = 14 + speed;
     }
     
     if(!Input.anyKey)
     {
         animation.Play("idle", PlayMode.StopAll);
         animation["idle"].speed = 2;
         head.transform.localPosition = new Vector3(0, 2.4f, 0);
     }
     
         if(Input.GetKey(KeyCode.LeftShift))
         {
             animation.Play("crouch");
             head.transform.localPosition = new Vector3(0, 2.1f, 0.6f);
         }
     
 }
