The goal -- a plate of cooked kadu from Food Corner Kebab. What is kadu?

They told me this was kadu at a Middle Eastern grocery store, but I think it's just some sort of gourd. Flesh is green and a little watery. I think they call all squashes and pumpkins "kadu," even summer squash, but it's clear to me that I am looking for winter squash or pumpkin (NOT Halloween pumpkin).
At another Middle Eastern grocery store, they told me to go to Super H, so I did. Found this:
Kadu (calaboza). This is the one you can buy in chunks at the ethnic grocery stores. Verdict, it's a little bland, somewhat starchy, and very similar in taste to what is sold in Afghani restaurants.
Kept trying. Could it be kabocha?

Kabocha. Verdict, too sweet, too dense, to be the kadu I was dreaming about.
Tried this one (no idea what it is, some sort of squash or pumpkin):

Again, too sweet, too dense.
Here's what it looked like cooked (might be the kabocha, I thought I had photos of all of them cut up and cooked but apparently not):

The closest so far in taste and texture seems to be butternut squash, but it's still not right.

Warning, cutting up and peeling the denser squashes like the kabocha is dangerous, they are tough and hard to cut without cutting yourself, which I did several times. I just read a recommendation to parboil first, submerge in a pot, put another pot on top to hold down if need be, sounds like it would work, but haven't tried yet. Recommendation is to parboil for five minutes, seems short. Then remove, let cool, and then cut and peel.
Not sure it would be a good idea to parboil a pre-cut piece of winter squash or pumpkin.
