I have been hunting for 2 days now, even finding the edge of the world, but have yet to find a jungle biome. I am trying to get jungle sapling and melon. While I know you can make jungle wood by burning rubber trees, that only give the wood not the sapling which is needed for tree breeding. I do plan on planting the jungle sapling around the Community center once I do find them so others don't have to hunt for days. If anyone has melon and/or jungle saplings please let me know and/or plant near the CC.
