Here's a story of how a Diplo saved my life, so, one day I was going on a metal run with my parasaur(I was low level) when suddenly my parasaur came under vicious attack from a swarm of angry dragonflies, soon it was devoured alive and I picked up its metal, but then I was too heavy to move, so I sat for a long time dropping things until I saw a huge creature with massive teeth running straight towards me! The creature turned out to just be a Diplo though so I fed him berries and used him to carry the metal back home,
Well I was walking to explore stuff, then I saw the diplo near the cliff. I found it cute and went near to check this dino on dododex. Sadly it happily yeeted me out of the world.
Kids, be careful near diplos, especially when you are near the cliff. They are kids-friendly dangerous. Just. Yeet.
So there was this Sarco and I had just tamed and had like a Level 10 Diplo. I had two Dilos and I just say the Sarco behind me. So I emergency whistle and get my Diplo just to smash the crap out of the massive Level 8 Sarco. My level 3 Diplo ended up killing it, but the Diplo smashed the thing. 10/10 would recommend this
