It has long been no secret for fans of Stardew Valley and Terraria that the developers are friends and often create mini-crossovers. Update 1.6 was no exception, introducing an Easter egg in the form of Meowmere to Stardew Valley's high-level content. This cute sword has long been familiar to Terraria fans as a Hardmode weapon capable of shooting funny cat heads. Now, Stardew Valley players can get their hands on it, too.
