Does anyone know how to mount it? I've been trying but nothing works.

Luigi: DONT WORRY IF I CAN OUTRUN MARIO 85 I CAN OUTRUN TERMINAL 7

(It's all in you're head Luigi, the Mushroom Minecraft kingdom isn't real.)
(It was never real, Luigi.)
{I know it's real, Mario! I- I}
{I'm kinda dying a little bit here, because I can't f***in' platform in first person mode right now, but Mario, I know it!}
(Luigi, you were just on a train, you were leaving Coney Island, you were going to Queens...)
{Oh no, Mario! It's kickin' in! The seven!- Wait, what do you mean i was going to Queens?! This is the Mushroom Kingdom!}

You got Terminal 7, Luigi.

Brain cancer.

I don't even know what it is, but it's bad.
