The Minecraft Iceberg

Welcome to the Minecraft Iceberg.
Anyone even you can add layers to the iceberg.
== Layer 1 ==
===Herobrine===
Herobrine was a Minecraft creepypasta posted on 4Chan in 2010 and later expanded on by Copeland in his stream.
===The Far Lands===
The Far Lands was a terrain generation glitch that happened in older versions of Minecraft prior to Beta 1.8. It soon got replaced by the world border.
===Height Limit===
Minecraft has a height limit. That's it.
===Disc 11===
Minecraft has several music discs. One of them is simply called 11. It's very disturbing but when it's put through a spectrogram you can see Steve's face and the number 12418. 12 is C in hexadecimal so it's saying C418. It also lasts 1 minute, 11 seconds and 11 milliseconds.
===Warden===
The Warden is a mob that is only located in the deep dark. It is very powerful and does half health with full netherite gear.
===Steve in other media===
Steve appeared in many other games like Super Smash Bros Ultimate, with his first debut being Zombie Town, an prototype game which obviously existed prior to Minecraft.
===Notch===
Notch was the original creator of Minecraft. He has left Mojang after the release of 1.8.1, this was also around when Microsoft took over implementing updates.
===Calm4.ogg===
This is a tune that Notch made for fun, and was rumored to be implemented from Alpha 1.1.1 to Alpha 1.1.2. At 1:36 in the track, you can hear a slowed down version of Notch saying "Mojang Specifications", which was the full name of Mojang from 2009 till 2010.
===Removed Potion Types===
On 29th September 2011, there were were a total of 32 base potion types. On 6th October 2011, this was finalised to the three base potions that we have now.
===Squids===
In Java Edition Beta, from January 14th, 2011 to March 31st, Squids could be milked with an empty bucket just like cows. This was a short mistake as Jeb used Cow to implement squids.
When first implemented, squids kept moving up, resulting in them flying in the air. This was later fixed, but for a while after that, until 1.8.
===Error 422===
Error 422, shortened to "ERR422" is a said possessed Minecraft version.
===Giant Alex===
Giant Alex was a myth where if you'll go to a specific seed in peaceful mode and swim to another continent, you can see the Giant Alex.
