Random mobs/rainbow sheep???

SO I was on about 20 minutes ago with shnaffle and gili and some random mobs and rainbow sheep kept appearing out of nowhere, and they were passive and couldnt be hurt, then disappeard. I took some screen shots the 4th time it happend:

Do you have the more mo creatures mod?

I don't and here's my brush with them. I almost had a seizure I was so shocked XD

It happened again in my office XD It was a lot worse in a cramped space...

I saw that as well, but i didn't pee my pants :lol:
