The observer is a little glitchy and bad/not useful. Not to lie but I didn't know which one was pocket addition, so this is on pocket addition. But anyways when an observer is looking at a fully grown water melon seed, it doesn't go off when it puts the watermelon to the side. Me personally, I find this very annoying for cool inventions and stuff I could build. But anyways if you read this, thanks, and love you guys. WClangfeldt
