More amphibious cephalopod and water pets!

Let us actually tame squids, axolotls, and other fish or even new ones, and have us be able to do something other than potions to keep them alive out of water, like use a slime ball on them or something like that and they can breathe and move on land just fine! Seriously you let in suicidal plant bombs, walking corpses, and literally the equivalent of HELL into your game and not this?
