I’m sure many people here loved having melon pets or Yoshi egg pets but wouldn’t it be better to have pets that real people have now like dogs, cats, birds and so on? Some animals like dogs and cats can follow you by walking or you could put them in their cages. Animals like birds can fly by your side, sit on your shoulder or go in their cages like dogs and cats.
(Edit: Also, it would be cool to change the dog model or another animal into your fav animal! For example I could make a dog look like a fox! )
