        Animation animation = this.GetComponent<Animation>();
        if (animation != null)

            animation[].speed = Random.Range(1 - speedRandomizationAmount, 1 + speedRandomizationAmount);
            animation[].normalizedTime = Random.Range(0f, 1f);
        //yield return new WaitForSeconds(0, .2f);
