When i was a little noob, i tamed 10 dilos. They wrecked absolutely everything. Carnos, titanoboas, you name it. Until that one fateful day, i recklessly took on a rex near my base. It was a fierce fight, and the dilos were losing. So i attempted to whistle the dilos to follow me. 8 dilos didn't make it. The last 2 dilos are still alive to this day, and they're both level 50 now.
