Just finished listening to the entire podcast. Lots of interesting stuff in there:
The giant goose mentioned in previous posts is the goose that laid the golden eggs (after all, Jack climbs the beanstalk and steals one from a cloud giant in the original tale). Wyatt apparently sat down and figured out how much the golden shell is worth by calculating its volume and translating that to a gp value.
There are monumentally huge giants called "giant scions" who are basically the near descendants of Annam. Wyatt suggests that they could be used in stories like a town being accidentally built on a long-sleeping one, or that some hold up the dome of the sky. Interestingly enough, they weren't among the creatures listed in the bestiary description a couple of months ago, so it's still left in the air if they are going to be statted out (I would imagine upper 20s CRs if they are) .
There will be guides on creating whole giant ecosystems, where giants, their giant pets, and other huge creatures such as dinosaurs dwell, and where human-sized visitors will be the equivalent to the size of house pets compared to everything else around them. I find this very intriguing and definitely look into reading this part!
