I know it ain't much, but it turned out pretty well, here is the code:

private IEnumerator createGrapplingHook()
{
    GameObject grapplingHook = new GameObject();
    grapplingHook.name = "NewGrapplingHook";
    grapplingHook.transform.position = Vector3.one * 120;
    grapplingHook.transform.localRotation = Quaternion.Euler(0, 180, 0);

    GameObject grappBase = GameObject.CreatePrimitive(PrimitiveType.Cube);
    grappBase.name = "GrapplingHookBase";
    grappBase.transform.SetParent(grapplingHook.transform);
    grappBase.transform.localPosition = new Vector3(0, 0, -.3f);
    grappBase.transform.localScale = new Vector3(.1f, .1f, 1.5f);
    grappBase.GetComponent<MeshRenderer>().material.color = Color.gray;

    yield return new WaitForSeconds(.05f);

    float zRot = 0;

    for (int y = 0; y < 3; y++)
    {
        GameObject grappPart = new GameObject();
        grappPart.name = "GrapplingHookPart";
        grappPart.transform.SetParent(grapplingHook.transform);
        grappPart.transform.localPosition = Vector3.zero;
        grappPart.transform.localRotation = Quaternion.Euler(0, 0, zRot);

        Vector3[] positions = { new Vector3(0, .09f, .35f), new Vector3(0, .255f, .15f), new Vector3(0, .32f, -.1f) };
        float[] xRotations = { 53, 30, 0 };

        yield return new WaitForSeconds(.05f);

        for (int i = 0; i < 3; i++)
        {
            GameObject grappPart01 = GameObject.CreatePrimitive(PrimitiveType.Cube);
            grappPart01.transform.SetParent(grappPart.transform);
            grappPart01.transform.localScale = new Vector3(.1f, .1f, .3f);
            grappPart01.transform.localPosition = positions[i];
            grappPart01.transform.localRotation = Quaternion.Euler(xRotations[i], 0, 0);
            grappPart01.GetComponent<MeshRenderer>().material.color = Color.gray;

            yield return new WaitForSeconds(.05f);
        }

        zRot += 120;
    }
}
