Not to mention the Nucklevee Grimm is probably seen as a myth, only its survivor's knowing about it/seeing it first hand (and it doesn't leave many survivors). The more likely possibility (indeed, the one we all came up with until we saw the hoof print) is that it was simply another mass Grimm attack, not one Titan Grimm.
