A 1986 monster movie spoof by Creator/{{Troma}} in which the eponymous creature emerges from its lair (guess where [[ExactlyWhatItSaysOnTheTin that is]]) and begins slaughtering citizens in a small Californian town. It's up to would-be newspaper reporter Richard Clark and scientist Diane Bennett to find a way of killing it. Very very campy, but doesn't take itself at all seriously, and is amusing if viewed in the right frame of mind.

Not to be confused with Spalding Gray's ''[[http://www.imdb.com/title/tt0102467/ Monster In a Box]]'', which is a ''completely'' different film.

!!Contains examples of:

* AbsentMindedProfessor: Dr. Pennyworth, to the nth power.
* AntagonistTitle: Clark is the protagonist.
* AxeBeforeEntering: The heroes are attempting to lure the monster into a trap, and are waiting at the end of a hallway, with the front door open to the outdoors. [[spoiler: The monster comes smashing through the interior door they are leaning against.]]
* BigBad: The closet creature terrorizing everybody.
* TheCameo: Creator/JohnCarradine plays a blind victim of the monster. Stella Stevens drops in for a quick parody of ''Film/{{Psycho}}''.
* ChildProdigy: 'Professor' Bennett.
* DaEditor: Played by Jesse White of "Maytag repairman" fame.
* {{Expy}}: The monster pretty blatantly steals some design ideas from the Xenomorph in ''Franchise/{{Alien}}''.
* ForScience: Dr. Pennyworth's attitude towards life in general. [[spoiler: It gets him killed.]]
* FrickinLaserBeams: 'Professor' builds one to use against the monster. [[spoiler: It doesn't help.]]
* GeneralRipper: General Turnbull.
* TheGlassesGottaGo: [[Franchise/{{Superman}} Clark]] "becomes" literally mesmerizingly handsome when he takes his glasses off.
* HotScientist: Diane, of course.
* ImpendingDoomPOV: Parodied.
* JawDrop: Diane, every time she sees Richard without his glasses. [[spoiler: And then the monster does it as well, and kidnaps him.]]
* JerkAss: Clark's fellow reporter Scoop; you're likely to cheer more when he gets his comeuppance than when the monster is defeated.
* LargeHam: The two leads are fairly subdued, but much of the supporting cast goes to town with this trope.
* MeaningfulBackgroundEvent: The monster lumbers into view behind young Professor while the latter is working in a school classroom.
* MonsterMisogyny / TouchOfTheMonster: Parodied; see Stealth Pun below.
* NighInvulnerable: The monster; it turns out the only way to destroy it is to [[spoiler: destroy every closet in the world.]]
* PoliceAreUseless: The sheriff tries his best, but..
* PunnyName: [[Creator/DickClark Richard Clark]].
* ShoutOut: The heroes try to kill the monster using an electrocution setup exactly like the one used to destroy the 1950's version of ''[[Film/TheThingFromAnotherWorld the Thing]]''. [[spoiler: It has no effect.]]
* StealthPun: The movie's title, assuming [[spoiler: the monster is male, which is never made clear.]]
