That didn't happen, creepers don't have rare drops
I had just emptied my inventory, except a map, sword, and steaks. I killed a creeper trying to stock up on gunpowder and in my on screen menu a single diamond popped up. If it was a glitch, bug, or some crazy circumstance so be it, but I hadn't even found diamond yet in my new world. It was in a field in between a jungle and desert. Since then I have gotten:
3 Power 1 bows
6 regular bows
2 iron helmets
3 iron swords
2 iron shovels
3 iron ingots
1 gold ingot
I made a chest just for rare drops so i could keep track of what is dropped.
The whole reason I started the thread was because it was odd and I wanted to see what other people got. I thought maybe since this was the XBox Edition that they might have added items to rare drops.
Are you playing in a world with other people? Perhaps someone else died right there and failed to notice the diamond when they collected their stuff or just even accidentally dropped a diamond (by pressing B at the wrong moment)? The best item I've gotten so far is a Power I bow. Other than than, just a couple regular bows, an iron sword (not enchanted) and an iron ingot. Nothing from a creeper other than the standard gunpowder.
The only rare drop I actually know of that I got (I don't pay much attention) is a bow from a skeleton. And the only reason I noticed it was because I had been playing not even two minutes on a new world when I encountered said skeleton right in front of a cave entrance. That was quite a nice experience since there was a lot of easily accessible gravel right next to the cave entrance, a few trees, and a bunch of chickens. I never got hold of a bow and a nice amount of arrows that quickly.

It is possible. I was playing with my wife, but when i told her she seemed surprised too. After killing hundreds more creepers, it has not happened again. It was just a fluke of some sort.
