Once you spawn you’ll see a huge jungle biome ahead of you. Turn completely to your right and start walking forward. Soon (based on your distance render settings) you’ll see the mesa biome.
As you reach the mesa biome you’ll have to follow it by the left side to get to the new and cool mesa spikes (as of version 0.9.5).
Please share your findings and other thoughts about the seed in the comments area. We love to hear from you guys!
