Kaalus has announced on his blog [Kaalus.wordpress.com] that there will be a new cetacean [animal of the whale and dolphin family] in the 1.26 update.
He later stated in the comments that this animal is a Beluga Whale! It will also be rare like the orca, meaning it will also have no spawn egg. It will be a carnivore, and spawn naturally far out in the ocean.
I am very excited for the new update! There are going to be so many new features, which will be discussed in later posts. Thanks for reading!!
