I saw some messages sent with multiple Notification sections, so something like:

 /*
    stdClass Object
    (
        [EnterpriseUrl] => https://ap.salesforce.com/services/Soap/c/29.0/00XXXXXXXXXXXX
        [PartnerUrl] => https://ap.salesforce.com/services/Soap/u/29.0/00XXXXXXXXXXXX
        [Notification] => Array
        (
            [0] => stdClass Object
            (
            [Id] => 0XXXXXXXXXXXXXXXX (Notification ID)
            [sObject] => stdClass Object
                (
                    [Id] => 0XXXXXXXXXXXXXXX (Object ID)
                    ... (Fields that you selected)
                )
            )
        )
    )

    Your object would be in: $args->Notification->sObject;
