There comes a time in any Murky's life (if they manage to survive that long) when they get an insatiable urge to breed. They then transform into filthy sluts that will screw anything with a dick. And that's how there are endless supplies of murlocs.
(Yeah, this started as an in-joke while playing Heroes and wondering why everyone hated Murky so much.)
Happy belated Easter, everyone!
