Having an issue with multiple animations on an object

So i have a simple projectile game in which you and the gorilla are going in the same direction automatically and you have to shoot him to keep him away. Now my problem is that i have two animations on the gorilla, one of him moving and another of him going side to side (dodging). My problem is that when i run the game the moving animation plays, but not the dodging one and he doesn't automatically move straight like he's supposed to with the script he just stays there.

Here is the script i was referring to. You pick a game object as the target and the player and gorilla move towards it.

 // The target marker.
 var target: Transform;
 
 // Speed in units per sec.
 var speed: float;
 
 
 function Update() {
     // The step size is equal to speed times frame time.
     var step = speed * Time.deltaTime;
     
     // Move our position a step closer to the target.
     transform.position = Vector3.MoveTowards(transform.position, target.position, step);
 }
