In ASA these killer pancakes are great for making orphans for you to adopt.

I was playing in the center and this 135 Theri had a child with it, the Theri was way too close to my base so I lead it to a nearby cliff to drop it into the water. So now it was in the water and I was about to go adopt the youngling but I wanted to look at my work, I peered down only to see the tickle chicken getting ganged on by some Mantas. I got the kill by shooting it with my cross bow.

So TLDR; lead the parent creature to the water with a pack of waiting Mantas then imprint of the newly orphaned csreature
