Companion update

Hey, there! There is an update that I want even more than the End Update, the Companion Update.

• They should add new real life creatures into the game as mobs that sit & stand. (dog, bird, hamster, hedgehog, goldfish, tortoise, guinea pig, etc.)
• I personally think that we have enough mountable mobs, & that we don't need more (horse, strider, nautilus, etc.)
• If possible, they should add custom tameable mobs along with the real life pets I mentioned earlier.
