So I just downloaded 14w34b snapshot server and had it running, and everything was fine. When I went exploring and went into a swamp, I had giant ghast-like things appear in front of me. I slightly wet myself but mustered the courage to find out what they were, and realized they were just bugged out sheep. I re logged and they were still there. I had not updated java in a while, and decided to update it after, and that seemed to fix the problem.

What I expected to happen was...:
A swamp with normal things inside

What actually happened was...:
Giant weird textured beasts that turned out to be sheep when approached. Made the sheep sounds and when killed would drop raw mutton and wool. Updating java seemed to fix the problem.

Steps to Reproduce:
1. Don't have the latest java
2. Find sheep
3. ???
