"If you have a big MacGuffin that pretty much protects your entire kingdom, you need to have a contingency plan in case you don't have the MacGuffin anymore!"The heroes have finally found the MacGuffin. After so much effort and Your Princess Is in Another Castle, they're going to return it, use it, or whatever they were supposed to do with it. Then somebody breaks it, making the whole endeavour pointless. A particularly frustrating form of a Diabolus ex Machina. The other characters' reactions usually range from shock to an anger burst. Double points if the MacGuffin can NEVER be replaced. In a story where The Good Guys Always Win, if the villain gets their hands on the MacGuffin, it's either taken from them or this happens. This usually happens during the middle of the series, not during a Grand Finale which would change the course of who wins. Often used in a Shaggy Dog Story. Contrast Dismantled MacGuffin, where the MacGuffin is not broken, but is meant to be put back together. Often leads to No MacGuffin, No Winner. This only refers to objects, so a Living MacGuffin (obviously) does not count.

As the Soul Dew controls the waters of Alto Mare, its destruction resulted in a colossal tidal wave that would've wiped out everyone in the city.

- A humorous example; in Ice Age, the gang spends a whole scene trying to get a watermelon from a "cult" of dodos so they can feed it to the baby they're protecting.

- The Books of Ember:
- In The City of Ember, the "Instructions for Egress" were mostly ruined by Lina's baby sister, Poppy, chewing on them; this turned what would have otherwise been a very quick and simple quest into a much more difficult and time-consuming ordeal as they tried to piece together what remained of the instructions.
- In The Diamond of Darkhold, Doon throws the diamond of Darkhold at a pack of wolves to save Lina. The diamond hits the rock that Lina is standing on and shatters into hundreds of pieces.

- In the Kim Possible movie, A Sitch in Time, Ron accidentally ends up breaking the villains' ultimate weapon, the Tempus Simia (Latin for Time Monkey), which he was warned could very well unravel the very fabric of spacetime itself.
