No, it's not a Minecraft animal in our fanart game cursor - Cubo is a brown dirt-colored colored cat with green on the top of his head and ears that looks very similar to a Minecraft grass block. This kitty can be obtained by buying a new cat with gems. When Cubo's puzzle is completed, it shows him in a Minecraft-esque scene where he lies on a throne made of stone with a crown on his head. On the left, he has a cube-shaped watermelon, and the window on this side also has GemDog peeking through. On the right, there is a window that shows a mushroom outside. The description says he is the king of crafting.
