"What was it called again?
You know, the grrreat, whopping whatchamacallit monsterrr that stopped appearrring, allowing old Windurst to returrrn to its peaceful state?
Back in the old days, when therrre was a full moon, the Tarutaru would lock and barrr theirrr doorrrs, too afrrraid to even peek outside."
