Which Floor Is Denny On?

Dear Diary,

Another Monday, another mystery...

The halls of Memory Den are always full of new adventures, and this week I've found myself a rather unusual hiding place. Every Monday I sneak off somewhere different, and it's your mission to track me down. 🗝️

Here's your clue:

An old machine still makes its climb,
Working loudly, time after time.
Though not for riders, up it goes,
To places only it now knows.

It visits one floor, then the next,
The third as well, it keeps you to guess.
Three places where I just might lay,
But which one? You'll have to say.

Look all around with watchful eyes,
The answer may come as a surprise.
High or low, don't pass me by,
You never know where Denny lies. 🗝️

Take your time and have some fun,
The hunt has only just begun.

May your eyes be sharp and your guesses clever. Until we meet again, happy treasure hunting!

Denny :)
