Ah the good old days,
When you awaken skeletron for the first time and lose thinking how on earth your going to kill him,
And the old man says he can't let you past,
But after failing with skeletron you realise you can get through the platform anyway,
And you think you're good and all by beating the system,
Until you get scared to hell by the dungeon guardian...
