Kiwiano

A Kiwiano is a roughly lemon sized yellow/orange vegetable from New Zealand.
They are covered in respectably sized spikes and are closely related to the cucumber, the plant that they grow on looking near identical.
The flesh under the skin is green and full of seeds that are very similar in design to those of a cucumber.
They are now also grown in places like California.

I just ate a Kiwiano, it tasted really weird.
