I was playing on the island map, and I got a high level one that I named Iggy. After some leveling Iggy was at level 203. I had a Ptera, but Iffy was way better. I went away for a bit, and when I came back to base I got the message: "Your Iggy - Level 203 has been killed by a Dilo - Level 100"
I went full speed back, and I sicked all of my tames on that Dilo. Since then, I have played on two different maps. Each time, when I see an Iguanadon, I check the level immediately. They are so hard to find. I did find a 120, but it got killed by a Carno.
So 10/10 would tame again. Assuming they don't get killed by a lowly dilo while its on passive...
So I was a level 34 noob trudging my way through the jungle, when I came to a clearing. I suddenly caught a flash of movement, and, behold, saw a pack of raptors chasing after a beautiful green iguanadon. I immediately wanted it for myself. I killed the four raptors with a pike and freed the beautiful iguanadon. Of course, I didn’t know that, If shot with a tranq arrow, it would attack me, so I did, and it attacked. I was immediately reminded of the way a kangaroo fights. Anyways, I managed to tame it, I name it marijuanadon. and many days go by. I build a pen for it. I leave and tame a spinosaurus. I take the spino for a hunt. I am heading home with a lot of meat in my inventory and I see the notification, “your marijuanadon, iguanadon, was killed by a carno. I desperately head back home. I see a carno, feasting on my beautiful iguanadon. Anger fills my heart. I pursue the carno. It already has low health because my iguanadon bravely defended itself. I take revenge. That is my story.
I just tamed my first one and realized it has unlimited stamina, I was running around and found Dilo, it kept attacking me so I gave it a poke in the eye with the thumbs, it said I could lvl up my iguanidon, then I saw that I could upgrade stamina..... so I did
