I tamed one of these named Diana. She was super fast but kind of stupid: always getting stuck on something. Diana and I formed somewhat of a relationship as time went on. Our bond strengthened she was able to beach a shark for me to kill it. Diana soon became one of my best friends... but nothing lasts forever. As I was leading her back to base via SS Dodo, I noticed a large figure swimming rapidly towards us. Diana made the fatal mistake of not paying attention to her surroundings. I helplessly fire arrow after arrow at it, but it was so filled with rage that they had no affect. I had to watch as MY Diana was ripped to shreds by an oversized fish. That is why my base is now called Fort Diana in honor of the brave soul. Thank you for your time.
The ichyosaurus is really hard to tame what i do is find a hight level ichthyosaurus and kill all the dangrouse creatures around it and start taming it with dodo kibble and raw fish meat you probably need a raft to go in to the ocean to tame this ichthyosaurus.
