Oh hello. Welcome to Durtle Heaven™.
It truly is a Crabsmas miracle you came here today.
You wish to descend into Durtle Heaven?
That’s fine with me.
I’m a pretty apathetic durtle.
But, deeper durtles won’t be so easy.
They will surely test you with their difficult jiddles.
I’ve never gone deeper than B2,
so my only advice is this:
If you run into any trouble,
make like your Review pile and don’t panic.
That is the most important thing.

Well, in you go.
The password to get to B1 is quite easy.
It, uh, rhymes with “ass-word.”
