There are no blocks whatsoever, indeed :(Are there no blocks in SG? Jeeze its been forever since I played it, I cant remember.
Also if you want a bird that talks you shouldn't get a blue and gold macaw. Blue and golds tend to be the most "chill" of the large macaws and can form bonds with multiple people. Other birds such as the African Grey and the Amazon Parrot tend to be more vocal, yet are smaller birds.
And, I want such a bird but unfortunately, I already have two cats and a dog :P (and some spiders and ants)
