I finally finished raising my baby giga and decided to take it out for a stroll. While using it to collect fish meat for my other dinos it ran out of stamina in the water “Alright no biggie I’ll just swim back to the surface and get my stamina ba-“. Your Level 260 giganotosaurus died. Turns out they have almost no oxygen (140 on mine) and swim incredibly slow AND lose an insane amount of hp when drowning for some reason. Don’t be dumb like me. Don’t lose your giga to the sea.
