More mobs

Hi, developers!

I have been playing Minecraft sinse 2013. Maybe it's long living game which I serially play.

So, get to the point. I think that this game need to more realistic and of course more mobs, both underwater and on land. Maybe in Minecraft should add shark, crabs (king crabs also), more fish types and kraken. What about mobs on land, I think should add penguins in ice biom, cause ice biom not seems such interesting. And add please ice fortress with ice dragon or ice guard, it's make interesting ice biom! 

PS: I would like to see it this year.
