Things In Cartoons That Are Actually Real!

 Animaniacs: In one "Slappy the Squirrel" skit, Slappy asks her nephew Skippy who is playing onstage, leading to confusion, because the band is called "Who". At one point, Slappy thinks the band is called "Yes" because an exchange went "Who's onstage?" "Yes." While on the surface, "Who" and "Yes" sound like made-up names, with the joke being that it's an absurd thing to name a band, The Who and Yes are indeed real bands

• In the Animaniacs (2020) episode "WhoDonut", one of Wakko's donuts had squid ink flavoring. While this seems like an odd flavor to most Western viewers, certain Asian countries use squid ink as food coloring to make foods look black

• The Berenstain Bears: In the cartoon version of "Get the Gimmies", the cubs want purple ketchup. This may seem like a made-up food, but it actually existed once (though was unpopular).

• In one episode of Freakazoid!, Freakazoid got trapped in a virtual reality arcade game featuring players running around a checkerboard floor shooting at each other while a low polygon pterodactyl flew around snatching them up at random. Sounds like the sort of nonsensical, out of date representations of video games seen in most media... except it's real Even the machine is drawn accurately.

Looney Tunes:

• Many people, especially those outside America, believe that the road runner is just a species made up for the Road Runner and Coyote cartoons. The truth is, there is an actual ground-dwelling bird named roadrunner living in North America. It doesn't help that the studio took great liberties with the bird's characteristics. (They're actually very small and sand-colored, not to mention they have a top speed much slower than that of a coyote.)
• Similarly, the Tasmanian Devil is also often believed to be a fictional creature, rather than an actual species of marsupial. Though to be fair, the only things the Looney Tunes character and the real animal have in common are their loud, grunting vocalization and ravenous appetite

• The Loud House: In "One Flu Over the Loud House", the flu spreads from humans to Charles, Cliff, Geo, and Walt. This may seem like an artistic way meant to amp up the creepiness factor, but the flu really can infect dogs, cats, hamsters, birds and other animals.

• Regular Show: In the episode of the same name, Tants  are a bizarre gift Pops gives to Mordecai and Rigby, pants that double as a table. Turns out, someone had actually already made a similar product in real life called Pic Nic Pants...and they arguably look more ridiculous than Tants.
