So here I was collecting rocks to make cement paste to craft a saddle for my new carbonemys. When all of the sudden two pteranodons come flying out of nowhere trying to kill me!

I only had one arrow left so I shot it at the pteranodons. I went to grab a melee weapon but I had no spears and my axe was currently broken. So here I am swinging my pickaxe at the pteranodons wondering why they were attacking (since they’re usally passive creatures). And eventually they killed me…

…but I went back to grab my stuff and it turns out I a pteranodon egg in my inventory. I guess I picked it up when I was collecting stones.
