I've recently been hearing about this mysterious "Entity303" guy in Minecraft. Apparently he was implemented by a fired Mojangster. let me just tell you right now... he is basically a piece of crud. Let me explain. First off, if you look up his skin on a skin searching website, he is just a Shy Guy from Super Mario. Also, he is apparently the new Herobrine. Herobrine was never real, so why would Entity303 be? Hey, what's that? Still not convinced? Well okay, let's keep going. Do you really think that a FIRED staff member would implement this? Plus, inspecting the Java Code of Minecraft won't reveal anything, as Entity303 was created by fans AFTER 1.7.10. I'm not entirely sure if he's in the snapshots, so I would say just play in 1.7.10 (That's what I would recommend under normal circumstances, anyways). And finally, any player on a server could take Entity303's skin, sneak, and hide in the distance. I hope I convinced you enough to realize that Entity303 doesn't exist. Until then, this has been Supersmith. Take care now. ;)
Ehh, I believe we know this already but, it's at least useful to those who still believe. Thanks :) .
