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.
"Funny Aneurysm" Moment: After first releasing Tatanga, Herman Smirch is ordered to take him and Princess Daisy out to lunch. Where do they go to eat? The World Trade Center. As if that's not enough, when they get there, a dark cloud is hovering above the towers. Does This Remind You of Anything??
Oddly, the Twin Towers show up in the Super Mario Bros. movie—when Koopa starts merging the worlds, his run-down pair of skyscraper palaces merge into the WTC.
And in the second Game Boy story, Tatanga and his minions hijack a space shuttle. The shuttle's name? Colombia.
The Scrappy: Stanley the Talking Fish, at least as far as Mario and Wendy Koopa are concerned.
