You can find melons in the jungle. So, it makes sense for a farm to be in that biome. With jungle trees integrated into the farm, this 12-slot fancy melon farm should make lots of melons for you. It also comes with tons of melons, from "running the farm" (actually just putting them in there for the screenshot lol). Now you don't have to use up steak when you don't need it!
Compatible with 1.5+, so it works pretty well in most versions.
