Wait! You just got an excellent idea!
You put some saltwater into your trusty syringe, and...
AAAAAAAAAGH WHY WOULD ANYBODY THINK THIS WAS A GOOD IDEA!?
Okay, so, that didn't work. Now what?
Old Bull Lee steps up and starts tapping away at his typewriter...
AND SUMMONS THE MIGHTY TUNICATE DOLPHINS!
The dolphins take the three of you to R'lyeh. Nothing particularly interesting happens on the way there.
You thank the dolphins and wave farewell to them as you reach the shore... or whatever that is. (It never occurs to you to have the dolphins hang around for a while in case you need to make a hasty escape, because you are a dumbass.)
Man, dolphins sure are nice, and totally not at all murderous or rapacious.
You suddenly hear a cry for help and run off to see what's wrong.
You find a small, panicky man. He manages to tell you his name between stuttering breaths; Randolph Carter.
What's his problem?
