the frog moves in the dirrection i press, but then it goes up again...

here is my code

using UnityEngine; using System.Collections;

public class PlayerMovement : MonoBehaviour {

private Animator playerAnimator;
private float moveHorizontal;
private float moveVertical;
private float turningSpeed = 20f;
private Vector3 movement;
private Rigidbody playerRigidBody;

// Use this for initialization
void Start () {

    //gather components from the Player Gameobject
    playerAnimator = GetComponent<Animator> ();
    playerRigidBody = GetComponent<Rigidbody> ();

}

// Update is called once per frame
void Update () {
    //gather input from the keyboard
    moveHorizontal = Input.GetAxisRaw("Horizontal");
    moveVertical = Input.GetAxisRaw("Vertical");

    movement = new Vector3(moveHorizontal, 0.0f,moveVertical);
}

void FixedUpdate () {

    //...then create a target rotation baced on the movement vector...
    Quaternion targetRotation = Quaternion.LookRotation(movement, Vector3.up);

    //...and create another rotation that moves from the current rotation to the target rotation...
    Quaternion newRotation = Quaternion.Lerp (playerRigidBody.rotation, targetRotation, turningSpeed * Time.deltaTime);

    //...and change the player's rotation to the new incrementel rotation...
    playerRigidBody.MoveRotation(newRotation);

    //if the player's movement vector does not equal zero...
    if (movement != Vector3.zero) {
        // ...Then play the jump animation
        playerAnimator.SetFloat("Speed", 3f);
    } else {
        //otherwise, don't play the jump animation
        playerAnimator.SetFloat("Speed", 0f);

    }
}

}
