How to grab and move all instantiated objects?

I tried to instantiate an GameObject already placed in scene. So I have Bullet, which is child of Player, player has this script attached. I dropped Bullet into the slot. I'd like to... actually, the script speaks for itself. I can't start game, so I don't even know if I fail at "GameObject theClonedBullet" or at "theClonedBullet.transform". I would like to execute theClonedBullet.transform.position += transform.right / 10; on every bullet instantiated. Is there way to grab them all? (there will be around 200 of them if not more).

Assets/Scripts/Player/FireBullet.cs(15,36): error CS0266: Cannot implicitly convert type `UnityEngine.Object' to `UnityEngine.GameObject'. An explicit conversion exists (are you missing a cast?)

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class FireBullet : MonoBehaviour {
5.     public GameObject Bullet;
6.  
7.     void Start () {
8.  
9.     }
10.  
11.     // Update is called once per frame
12.     void Update () {
13.         if (Input.GetMouseButton (0)) {
14.             Vector2 originalPosition = new Vector2(Bullet.transform.position.x, Bullet.transform.position.y);
15.             GameObject theClonedBullet = Instantiate(Bullet, new Vector3(0, 0, 0), Quaternion.identity);
16.  
17.             theClonedBullet.transform.position += transform.right / 10;
18.         }
19.     }
20. }
21.  

For my defense, I was Googling it, hence the middle line, but then it complains about something else.

 

Change this:

Code (csharp):

1. GameObject theClonedBullet =Instantiate(Bullet, newVector3(0, 0, 0), Quaternion.identity);

into this:

Code (csharp):

1. GameObject theClonedBullet =(GameObject)Instantiate(Bullet, newVector3(0, 0, 0), Quaternion.identity);
