These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Duck Hunt
Adaptation Displacement: The game is actually based off of clay pigeon shooting gallery toys Nintendo made in the 60's and 70's. Perhaps one of the most potent instances of this trope - not only do most people not realize this game was based on a toy Nintendo used to produce, most people aren't even aware Nintendo produced toys in the first place.
Urban Legend of Zelda: No, you never get to shoot the dog, no matter what level you reach — unless you play the arcade version's bonus round, where you have to try your hardest not to. Or consider the loss of points Worth It anyway.
There are some sources that say the dog has a name and it's "Mr. Peepers". It still fit the trope, as there's no official statements and it's simply known as 'The Dog'.
