My new favorite fruit

We just got introduced to a new fruit this last month.  We have no idea what the English name is, but it has a crazy long Bislama name:  nandule ndule and the language name is taure (tow ray).  It can't really be compared to anything else I know.  The texture is maybe most like a pear but the taste is sweet and not so grainy.  Delicious!  It comes in this shape and a tiny baseball sized pumpkin shape too.  You can eat the skin and flesh, but not the seed.  We hope to plant some around so we have our own in a year or two!  If you recognize it, let me know what it's name is in English!  :)
