The Worst Best Cache

We have a cache in the North Island that guarantees an FTF for everyone. The cache is at the Firth Tower, and it is called Firth To Find. FTF. Brilliant, right?
Maybe not.
In the same spirit, allow us to present the Worst Best cache, ever.
Yes. We mess with your mind. Just clock the smiley, and don't expect fireworks or party balloons to drop from the sky.
"Why all this negativity?", you may ask. Well, Some years ago, not far from here, was The Best cache. And I managed to make that my first ever DNF.
As you can see, I'm still working through the issues.
You won't DNF this one tho'.
