If I had a penny for every time World of Warcraft players start killing frogs en masse, I'd have two, which isn't alot but it's weird that it's happened twice. An area of the new Midnight expansion happens to have endlessly spawning amphibians, creating ample opportunity for people to dial up the numbers on their skinning stat.
You can find this water slaughter going on near Silvermoon City, at the Stillwater Pond. There, Gloombelly Toads are in ample supply, because once you clear them out, more just keep coming, as if they're breeding within minutes.
