Why are these good ideas:Imagine waking up and sending your personal pet penguin to get some fresh fish for lunch personally i love this idea and so do many of my friends and if you disagree then so be it
This is quite vague, and has very little detail to begin with. The idea of taming it and having it catch fish for you feels quite redundant because we have Fishing Rods. Unless you go into further detail of how the penguin catches fish, it could have some possibility. But for the penguin to be useful in just catching fish feels like a waste of potential for this mob. Please add mob statistics (health, spawnrate, chance of taming), how it's fishing mechanic works, and why do you think we should have these mobs.
