Bust Monster:
A most curious relative of the armor destroying rust monster. The bust monster's tentacles have the uncanny ability to grant a bodacious pair of breasts to its victims at the slightest touch. Upon finding a humanoid creature it perceives as not well-endowed, the bust monster will leap into action and attempt to stab at its targets chest with its magic tendril. A set of big, perky tits will emerge, shredding through tight clothing and possibly causing back discomfort in the victim. Be warned: Do not enrage a bust monster. Its tendril can grant breasts anywhere, not just the chest. If it goes on the offensive, an unlucky adventurer might end up with breasts on their hands or their forehead or anywhere else the monster touches them. If you come into contact with a bust monster, act quickly. Take off your socks, gloves, or cape and stuff them under your shirt. If you convince the bust monster you have a nice pair of big naturals it's likely to leave you alone.

Mother Mimic:
Some mimics are cunning hunters while others are more civil. A mother mimic is somewhere in between. When a mother mimic catches an adventurer, it puts the adventurer through a strange metamorphosis instead of eating them. Using its transmogrifying internal fluids and hypnotic suggestion, the Mother Mimic molds the adventurer into a comely new form called a Daughter. The daughter is then set loose in the dungeon with one purpose: Lure as many adventurers as possible to the Mother Mimic. The daughter can accomplish this in many ways, but often the offer of sex will suffice. Whether the Mother Mimic makes more daughters or simply eats the extra adventurers is up to the creature's prerogative.
