This is a Kiwano:
I obviously had to get it. Is it like a kiwi and mango delivered in some strange spiked vessel?
But they were quickly dashed when I tried some. Slimey, salty, sort of frothy at the same time. Not a happy mouth feel. The flavor was somewhat cucumber-melon like...but it was certainly lost to the texture. It felt like eating snot. Ugh.
So if you come across one of these bad boys. Be wary.
