An accidental tame!

So,I was searching the whole ocean for Sea Giga aka mosasaurus with my Basilo.He was so slow that I thought it will be easy for me to find Mosa,but no luck,so I grabbed my ictchy which is much faster in search of Mosa.Ichy is handle with care creature,so I tried to avoid most threat in search of mosa.Now,in deep sea adventure I encountered a lot of megs and this plesiosaur, just ran away from them at first glance and kept searching then suddenly a highest lvl (450) plesi appeared and then I saw my inventory I had 400 Toxicant arrow.So, I grabbed my ascended Compound Bow and started to knock out it making sure it's struck.And it took me 48 arrows with ascended Compound Bow.So this is how I got my Highest lvl plesio but that come with sacrifice of my ichy it got killed by jelly when I came to surface to find taming food for plesio

AND THE JOURNEY CONTINUED TO FIND THAT MOSA
