Open discussion: What would a dungeon look like if it was made and run by a certain monster girl?
Hakutaku: Dungeon is a massive library turned into a labyrinth of bookshelves and walls of tomes; all the various traps and doors and so on can only be dealt with by answeering various trivia questions, which get harder and harder as the dungeon goes on.
Phantom: The whole dungeon is just one large empty room, with the phantom using her illusions to generate the hallways and doors and monsters and everything else a la the Holodeck; gives a running commentary the entire time,
Wurm: Dungeon consists of various tunnels and holes that Miss Wurm has dug, treasure consists of various nice rocks that she's found while digging.
Wight: Dungeon is her summer home turned into a dungeon, with all the furniture wrapped in plastic; speakers are built in the walls that play her pre-recorded noblewoman's laugh whenever the adventurers make a mistake or trigger a trap or whatever
Anubis: Dungeon requires paperwork be filled out for each door smashed in, room explored, and chest opened
Kunoichi: Dungeon is actually a training school for apprentice kunoichi; teachers think that hands-on experience fighting adventurers is the best sort of learning.
Mimic: Hundreds and hundreds of chests, one or two of which actually have treasure in them.
Fairy: Dungeon is fairy-sized, no actual way for adventurers to get in without shrinking magic
Cheshire Cat: Designed from top to bottom to be as annoying as physically possible; walls are constantly moving to make it impossible to map the place, all the treasure is fake, random teleporters in the floors scatter the party and get them lost, etc.
Mad Hatter: Dungeon is absolutely filled with various kinds of hallucinogenic mushroom spores, party invariably trips balls the entire time
