Minecraft wiki entry for Melon, associated text: In Bedrock Edition any stem adjacent to a melon block appears connected to it, even if the melon was not grown from that stem.[3] Therefore, if a melon block generates between two stems, it connects to both of them. Pumpkins also do this, although they do not connect to plants of different species.
Unlike other versions, the New Nintendo 3DS Edition is the only version that has a reversible crafting recipe for the melon.
Minecraft melons greatly resemble square watermelons in real life.
