Tip: if you want a good counter against these guys, use a Yutarannus. Their roar automatically unburies them, and I don’t think they’ll be able to knock you off if you’re riding it. I’m not entirely sure
One day, I was in the redwoods with my assault rifle killing terror birds, and then out of nowhere, this boy jumps out and scares the flip out of me. So I run back to Pterry Cruise, (my pteranodon) and fly as fast away as I could. I circled back and filled him with holes.
