Can YOU Guess EVERYTHING wrong in this Minecraft video?

Me and 2 of my friends are about to beat Minecraft. However, not all is what it seems. In our quest to beat the game, we have cheated! On 10 separate occasions we have done something impossible in a vanilla world of Minecraft. Maybe we've edited a texture, maybe we've spawned something in that we shouldn't have. No matter what it is, I'm challenging you to find all the mistakes. Can you find them all? Watch and find out!
