Here is 2 stupid things I did like the moran I am >:(
1 I was riding my argentavis and it was night so I landed on a rock,without a light to show me danger I was scared of everything then I heard a "Pat Pat Pat Pat" and I was so scared I looked in the direction of the noise and slapped it,when I did,I heard the dimorph noise and screamed as I flew as fast as my birds wings would take us(we survived)
2 i was riding my trex,and it was day so I was tired of walking and sprinted and y'know when u cant see anything in your path so u trample it half to death? I did it- I trampled a dimorph,luckily I stabbed him in the heart with my pike :'D (my trex and me survived)
I have a pack of 10+ high level dimorphs that eat brontos and rexes before their corpses can hit the ground, I have them follow me on my argy and when people see the cloud of sky piranhas behind me they give me wide berth as they attack riders directly. If you have a base with a large closed room have these guys follow 1 dino that is passive but set all the dimorphodon on aggressive, no one will want to go into that room.
