Hi guys,  
so I am using this code on my symbol:  
onClipEvent (load) {  
height = 150;  
width = 500;  
cx = this.\_x;  
cy = this.\_y;  
}  
onClipEvent (enterFrame) {  
this.\_x = cx+(1+Math.random()\*5);  
this.\_y = cy+(1+Math.random()\*5);  
}

but I would like to apply a tween effect at one point on the timeline, were the mc vibrates but moves out of screen or transitions in scale.

How would I go about this?

Thanks!
