It is likely a matter of personal preference, but to me a giant form of a naturally-occurring creature seems like it would be beast if it has beast-level intelligence. However, if a giant form of a creature that is a beast is highly intelligent, that seems to suggest some magical origin. Given that giants are not necessarily smarter than humanoids simply because they are larger (hill giant, ogre), the giant category would not have been my first pick. But, as I said, it's likely one's preference that will be the determining factor.Right, I’m 100% onboard with sapient animals not being classified as beasts. I’m just not sold on celestial being the right alternative. Again, the Giant type exists, and I think would be a better home for these sapient animals, since all of them are, in fact, giant.
