End Of Level Boss pt. 2

I walked in with a collar
But I left in a cape
I bought a ticket for the opera
Then went into a rave

It's a pill of two halves
And a peculiar taste
Can you ask the krankenschwester
How long I can stay?

And now there's nowhere left to hide
And only things to run to
Don't pretend you didn't realize that this was
What it would come to

I took a minute to collect my thoughts
But there was none to be found
So it's slowly down the corridor
Where they will put this dog down

I'm not offering a lifeline
Just forewarning of the truth
All aboard the HMS Impending Doom
It sails soon

I'm not offering a lifeline
Just forewarning of the truth
All aboard the HMS Impending Doom
It sails soon
