Display text on Cloud sprites

By the following script I randomly spawning my clouds into the screen. Now I want to display some text on cloud sprite. Text will be different for every cloud and move with the cloud. Please help me out how can I do this?

 using UnityEngine;
 using System.Collections;
 
 
 public class CloudSpawnerScript : MonoBehaviour {
 
 
     [SerializeField]
     private GameObject[] clouds;
     
     public float distanceBetweenClouds = 2.0f;
     
     public static float minX, maxX;
     
     private Player playerScript; 
     
     public float lastCloudPositionY;
     
     [SerializeField]
     private GameObject[] cloudsInGame;
 
     [SerializeField]
     private GameObject[] collectables;
 
     
     public float lastPositionX;
     
     private int controllX;
 
     void Awake(){
 
         Vector2 t = Camera.main.ScreenToWorldPoint (new Vector2 (Screen.width, Screen.height));
         maxX = t.x - 0.5f;
         minX = -t.x + 0.5f;
         
         float center = Screen.width / Screen.height;
     
         CreateClouds (center);
 
         for (int i = 0; i < collectables.Length; i++) {
         
             collectables[i] = Instantiate(collectables[i]) as GameObject;
             collectables[i].SetActive(false);
         }
 
     }
 
 
     // Use this for initialization
     void Start () {
 
         playerScript = GameObject.Find ("Player").GetComponent<Player> ();
         cloudsInGame = GameObject.FindGameObjectsWithTag ("Cloud");
 
 
         Vector3 temp = new Vector3 (cloudsInGame [0].transform.position.x, cloudsInGame [0].transform.position.y + 0.6f, playerScript.transform.position.z);
         playerScript.transform.position = temp;
 
 
     }
 
     void OnTriggerEnter2D(Collider2D target) {
         
         if (target.tag == "Deadly" || target.tag == "Cloud") {
             Vector3 temp = target.transform.position;
             Shuffle (clouds);
 
             
             for (int i = 0; i < clouds.Length; i++) {
                 
                 if (!clouds [i].activeInHierarchy) {
                     temp.x = Random.Range (minX, maxX);
 
                     temp.y -= distanceBetweenClouds;
                     
                     lastCloudPositionY = temp.y;
