I was making a circus thing and while I was building it I blocked up the door with iron blocks (It was creative mode) there were some rainbow sheep in there, one named Dinnerbone, one Grumm, and one jeb_. I also had a creeper named Boomie in it. I deleted the door to get out and two of these things went everywhere. This is just a picture of one of them, and its squirming around in that hole. It doesn't seem hostile (Of course, I'm doing creative mode and I tamed a zombie pigman, enderman, and a friggin creeper) and its quite fast when not stuck in a hole.
What's it called? I'd wiki it, but then I'd need to search its name and that I don't know.
I chose the category because Minecraft is entertainment. HIGH CLASS. PIXEL-Y. ENTERTAINMENT.
