Mystery fruit

As often happens, I took this photo of something that was new to me and jotted down its name on a small piece of paper. I now have enough tiny pieces that I could wallpaper my computer room walls and can't find anything! If I ever remember when I'm in the ENMAX Conservatory at the Calgary Zoo again, I'll write down its name ... on a little piece of paper that will no doubt join the other thousands that surround me in this room, lol.
