Mars Wants Chocolate
Image by rafikemil (FB). Used with permission.

Earth is not the center of the universe, but nonetheless it is special - we have a precious commodity. No, not our nubile Earth women. Something better.


Turns out, our common comestible X is an Impossibly Delicious Food to aliens, who go to absurd lengths to acquire it. UFOs are smuggling candy past border checks. Alien abductions happen because humans might have Hershey bars in their pockets. Cattle mutilations? Aliens will NOT give up until they figure out how to extract chocolate milk.

Chocolate is a common target, but almost any Earth snack food can be used here. Chocolate (or other snack foods) might be a Power-Up Food to the aliens, but if they need it to power their spaceships, it's What Do You Mean, It's Phlebotinum?.

Not to be redundant, this has nothing to do with the nougat bar and the confectionery company making said nougat bar.

  • This is how SG-1 manages to open trade with the Tollan in XSGCOM. Earth doesn't really have anything that the Tollan want, until someone makes an off-hand comment about how the first global trading empires on Earth were built around spices and luxury foods. SG-1 decides to send a few crates of various spices, wines and sweets through, and distributes chocolate bars to a class of school kids as a goodwill gesture. The kids' reactions are enough to get a number of entrepreneurially minded parents to start lobbying for a trade agreement as soon as possible.


  • In the Young Wizards series, chocolate has a variety of effects on different alien species: it acts as a drug for some, but others just like how it tastes. It's also the real reason UFOs visit Earth. In the eighth book, Carmela forces an entire battalion of aliens to back down by threatening them with a wrapped chocolate bar.
  • In The Company Novels, chocolate (referred to as Theobromos) is the only thing that can intoxicate the time-traveling operatives. Hence one character having a "dealer" in premium chocolate.

  • The infamous E.T. copycat Mac and Me contains a rather egregious example: it seems that the liquid MAC and his family drank on their home-planet is the equivalent of Coca-Cola, of all things, to the point where the drink can be used as a medicine for them, by kids, no less. MAC also eats Skittles at one point. Yeah, this movie is rather infamous for its ridiculously in-your-face Product Placement.
    • Given the blatant pandering towards McDonald's, you'd think they'd also be on the aliens' menu. But surprisingly (and thankfully), they aren't.


  • In Animorphs, Ax imagines that one day the other Andalites will come to Earth just to eat the cinnamon buns. Having a mouth makes him go crazy for everything, but those are his favorite.
  • In I Was A Sixth Grade Alien, the aliens visiting Earth want to find a reason to establish friendly relations with us, but we don't have anything they actually particularly want. Until, that is, they discover peanut butter. Not because it's so delicious, but because it supercharges their romantic and sexual drives.
  • In Roger Zelazny's This Immortal, the aliens view original-formula Coca-Cola as humanity's second-greatest contribution to galactic culture. The first being a new and interesting problem in the social sciences, namely, what to do with a species who managed to ruin their own homeworld. (They also apparently appreciate poetry).
  • Hal Clement's Ice World. Aliens (who live at a much higher temperature than humans) discover that burning tobacco is an extremely powerful and addictive drug to them. They violate their civilization's laws to smuggle it off Earth.
  • Fat Men from Space by Daniel Pinkwater has Earth being invaded by aliens who look like fat men and steal all the junk food on the planet. Pinkwater's plunderers are particularly partial to potato pancakes.

  • Supernatural: Downplayed, where the Grim Reaper (who notes that he does visit alien planets) decides to ignore Lucifer's orders to wipe Chicago off the map and killing millions more during the Apocalypse. One of the reasons he gives for this is that he likes the city's pizza—this Death is a fast food junkie.
  • During the brief period that they spend on Earth in Farscape, Rygel quickly becomes addicted to candy of all kinds.

     Newspaper Comics  

  • In one Calvin and Hobbes comic, Calvin disguises himself as an alien.

    • The Bleen conquered a quarter of the galaxy for cake, though apparently every carbon-based species (except the Lattrox) makes it.

     Western Animation  

  • In Futurama, one of Earth's more notable creations is apparently the pizza bagel.
  • Cartoon Network had a Cross Through event in which each of the network's top shows at the time had an alien invasion plot. What were the aliens after? Cheese.
  • Invoked on Invader ZimTak wants to steal Zim's mission to prove she's the better Invader, but Earth is useless to the Irken Empire. However, since all Irkens seem to be junk food addicts, she plans to make it useful by hollowing it out and filling it with snacks. The normal version of this trope is totally Averted, however, since human food actually hurts Irkens.
  • In Megas XLR, Earth is apparently renowned throughout the universe for the snacks and beverages available at convenience stores, and extraterrestrials with Earth currency frequently visit incognito to purchase them if they're passing near Earth.
