Welp i said what i was going to do and so behold! Giraffes! Plesiosaurs! Giant Sea Turtles! AND MOST IMPORTANTLY AFAT PUG!!!! (to apologise for the giant arachnid. Have fun slaying that thing.)
Zaratan, (Sea Turtles/Archelon)
The Nope, (Whip Scorpion)
There will be more (I know @shoddymoddy and @niklisson both want cat grimm). Honestly, I’d end up doing an entire post on prehistoric and deep sea grimm because that map of Remnant has a lot of water and many islands so naturally there would be grimm to reflect the animals in those environments.
