Warden is a new hostile mob with interesting features, that make gameplay around him unique. For starters, he is completely blind but has very good hearing, which makes him react to every sound. If he will find out that you're wandering somewhere close by - he is probably going to kill you. However, there is a way to avoid death by Sneaking by past him. Warden is a fun new mob that is going to change the way we play Minecraft PE, and the addon allows you to test it right now.
