101 Unusual Mimics
1. Mimic as the keystone in an arch (build by mimic minions). When it attacks and jumps free not only it there a bitey mimic, the room's ceiling collapses on you.

2. Mimic treasure map. The mimic pretends to be a treasure map that leads you to am ambush of the mimic's allies. The mimic changes this location as needed to keep the news from getting out.

3. Mimic bandage. It just quietly drinks your blood when you wrap it around your wound.

4. Mimic haute couture. The mimic rents itself out to be brand-new, impossible-without-living-cloth high-end outfits and shoes that fit perfectly, match your coloration, hair, and jewelry, and you don't have to put in a closet after wearing once. Hourly or daily rates available.

5. Mimic rope. It waits until you are using it in a life-or-death situation, then extorts you with greater payment or it withdraws its (literal) support.

6. Mimic golem: Easiest to pretend to be a wood golem or clay golem. You think it's a construct, but it's actually an aberration, giving it a distinct tactical advantage.

7. Mimic rock at edge of common rest-stop campsite. Look, people are SUSPICIOUS of treasure chests these days, but no one looks twice at a rock that happens to be near where their head is going to be when they sleep.

8. Mimic false bottom of a chest. Go ahead, check the chest for signs it's a mimic all you want. then, once you are inside and your guard is done, and you get excited you've spotted a false bottom...

9. Mimic hanging tapestry. May rent itself out to high-end castles as a magic every-changing tapestry that also shouts an alarm when people find the concealed door behind it, or may drop down on unsuspecting adventurers looking behind it for a concealed door. Or both.

10. Mimic trash-can private investigator. You can learn a LOT about someone by sorting through their trash, and if they give it to you there's no expectation of privacy.

11. Mimic Spike at the Bottom of a Pit. If you fall into the pit and still look fine, it ignores you as too tough to handle. If you fall into the pit and seem badly injured or incapacitated...

12. Mimic bookcase wizard. People have been placing powerful and dangerous books on it in the forbidden section of the library for decades.

13. Mimic altar. Honestly, a faithful devotee of a god that has decided to serve as an altar. Of course, if you come to DESECRATE that temple...

14. Mimic Kitchen Table. Mostly just eats scraps when no one is looking. But may be in trouble since it is now so fat, it doesn't really fit in the same space anymore...

15. Mimic Mirror in a Vampire's Employ. Look, some vampires care how they look!

16. Mimic Siege Tower. Always the right size and shape to reach the top of a wall, able to become a bridge to get over a moat, and able to be healed or buffed against fire with "1 target" spells.

17. Mimic Wagon. Mostly lets your draft animals pull it along (while it dozes off), but for an extra fee and turn into a boat to cross rivers, walk itself out of mud, and so on.

18. Mimic Wine Barrel. Takes a nip now and then, but mostly stays sober so it can eat the occasional vagrant that wonders by late at night, who no one will miss.

19. Mimic Wishing Well. I mean, people just THROW money into it! Why risk combat when you can get paid to sleep, then go buy any food you want later?

20. Mimic Coffin. Sneak into undertaker's (or cut deal with them). Get corpse placed indie me. Eat it. Dig my way out of grave, making people panic about ghouls. Sneak back to undertaker's.

21. Mimic Iron Maiden. Tortures put people in me, I drink their blood, and they are kept alive to go back into me again and again.

22. Mimic smuggler. Can look like any crate, fake any needed seals or markings, hide among other crates and shuffle from warehouse to warehouse and hold to hold as needed.

23. Mimic roulette wheel. Doesn't detect as magic or illusion, but can still make sure the house gets more than its cut (or, if smuggled in as a ringer, it's partner can take a huge bite out of the house).

24. Mimic Spymaster Confessional. Look, if there's a place people are going to just whisper their secrets anyway...
(Lots of other Mimic Spy possibilities, too.)

25. Mimic sleeping bag guard hireling. Hires itself out to protect travelers. It can sleep during the day, eat all your leftovers, and quietly watch over you while you sleep at night, while being the perfect size and warmness for you.

I really didn't mean to write 25 of the #101UnusualMimics in 43 minutes, but I let me antibiotic-addled brain take me WAAAAY off task. I'll finish up the remaining 76 of these another time.
