You'll recall that in Godzilla vs Kong there was a really big skull in Kong's temple. There are many theories discussing what this skull might have been, or who it really belonged to. The answer isn't clear but in this episode Joe and Jacob present hints that suggest that it was indeed belonging to a Godzilla or a relative of the "gojira species". Be wary that there is a lot of speculation when it comes to this topic, but if you are open minded and in for a good listen: Enjoy!
