This thing is more dangerous that Matt from Wii Sports mixed with Chuck Norris. I have over 12 years of playtime and I haven't even been able to make a stone pick yet because these ferocious little bugger devour me alive. One of my friends came to help out with his titanosaur and 12 gigas but the did only got angry. Do not engage these beasts.
I was trying to tame a dodo and built the gate trap too close to base. When I shot it with the first dart it went crazy and destroyed half our base. We lost a Rex in the chaos that followed. When attempting to tame this build the trap as far from base as possible.
Imagine A chicken on steroids this thing will lay around 25-50 eggs every hour and that's about all it's good for. A must have for any tribes looking to take to the sky however, as their eggs make getting a Ptera much easier.
