Elementary Event Chain

I'll explain this, someone does something and the next poster writes a catastrophic consequence of the action, and the next posts another consequence and so on. Please don't be too exaggerated posting things like "the universe explodes", anyway, if someone does, a new action will be posted.

Let's start hdgavxiwp:
LED42 climbs a hill.

He finds out the hill is part of the background and it falls under his weight, and LED42 dies.

Koops enters Bowser’s castle.

YES, YAY!!! SOMEONE FINALLY REPLIED TO THIS! HOORAY!!
I think it's better this way, someone does something and the other posts a consequence and another action, and so on.

Koops reaches the bridge where Bowser is, and he cuts the bridge. He falls to the lava as well as Bowser.

LED42 purchases a Santa Hat
