Okay, so, I'm sorry. I really am.
"Crablor" is a meme in the Silmarillion fandom wherein Maglor, during his years of wandering in regret by the seashore, turns into a crab cryptid. They have a whole week for it and everything.
Last night, whilst dreaming, my subconscious put two and two together and came up with crab. And so I woke up with the dumbest crossover bunny ever, and I must exorcise by writing it down. At least it's brief.
