In Minecraft 1.1 there's been the addition of eggs. Everything can now be "hatched" (including Villagers...) I've started a new (flat) map to have a play around with epic creeper battles but can't get hostile or nether-based mobs to spawn. The "Enderman" egg results in the purple particles showing, and the ghast egg produces a ghast scream. I thought about they can't survive in the sun so I built a little shelter for them...still no luck. I tried digging a hole far down to see if I could get a slime to spawn but didn't realise the shallow depth of an ultra-flat map and fell out to my death.
How do I get the evil beasties?
