I think it will be funny if he added herobrine for a week without telling anyone.
Example:
*Guy sleeps*
*Herobrine comes up and wakes up*
*Guy screams and starts waking Herobrine with whatever object he was holding when he went to bed*
*Herobrine pushes back into bed*
*Wakes up, screaming out of house not wanting to sleep ever again*
I mean winter bioms have snowmen , summer bioms need one too!
Example:
*Guy sleeps*
*Herobrine comes up and wakes up*
*Guy screams and starts waking Herobrine with whatever object he was holding when he went to bed*
*Herobrine pushes back into bed*
*Wakes up, screaming out of house not wanting to sleep ever again*
How about just certain features, like the Nether updates and snow golems?
