Well how about this? Jens Bergensten, the lead developer for Minecraft at Mojang, has just added a new biome: the jungle. It obviously looks like a forest biome combined with a swamp biome. This new biome will be included in today's Minecraft Weekly Snapshot, so you can play under the trees. Perhaps the most interesting fact that Jeb shared was that he will add jungle mobs to the game eventually. Sounds awesome, right?
