I was climbing the mountain in the redwood forest, and I could hear the gargle noises these guys make, but I couldn’t find them. I spent about five minutes looking around the mountain for them.
Turns out there were two of them staring down at me from the summit. I wasn’t in their aggro range yet, they just happened to spawn facing downwards, like they were watching me. It was the funniest thing I had seen in this game in a while.
Long story short, I tamed one of them and named him Watcher. I love these dinosaurs so much.
