You might think that taking actual people out of a movie means taking the mistakes and human error out with them. But anyone paying close attention to modern animated films knows that even the smallest mistakes seem hilarious considering someone made them one frame at a time. And the bigger the mistake, the better it is to search for. Here are 20 Massive Mistakes in Animated Movies.

Zootopia

The animals may have evolved to walk and talk, but math is still a problem. Predators make up just 10% of the population, but assistant mayor Bellwether later claims that they're outnumbered 10 to 1. Hopefully kids didn't take that as a math class, since 10% means a ratio of 9 to 1, not 10.

No older fan of Zootopia can forget the cameo from actor Tommy Chong playing the mellow Yax, one of the city's "Naturalists" - the word the writers were looking for was actually "Naturists" another words for nudists.

The Lion King

The age of hand-drawn animation may be all but over for Disney, but some awesome mistakes remain thanks to one animator. Look closely when Mufasa is filling Simba in on the kingdom, and you'll notice the label "45" appearing on screen for two frame. And you'll wonder how you never caught it before.

Beauty and The Beast

Nobody fights like Gaston - or talks like him. His lips don't match his words in his final fight with Beast, since his line - "Belle is Mine" - was originally "Time to Die." Softening the tone makes sense, but the original animation was left behind.

The Good Dinosaur

The movie may be set in an alternate history, one where the asteroid that killed off the dinosaurs 65 million years ago passed by completely. One problem though: the hero Apatosaur and his family went extinct over 50 million years before the asteroid ever struck.

Wreck-it Ralph

It isn't an animation glitch or error that gives Wreck-it Ralph its funniest mistake, but time itself. Think about it: did you ever notice that Ralph makes a jump into Hero's Duty as the arcade opens, only for it to close just minutes later? Either time passes faster in the game, or it's an editing shortcut audiences aren't supposed to catch.

The animators went to serious lengths to fill the movie with video game cameos and details, but a few mistakes slipped through as a result. The sign at Game Central Station clearly says that "Burger Time" is Now Playing - but nobody told the star chef, serving pie to Q*bert and his friends.

Frozen

As much as we'd like to believe that the famous "Let it Go" musical number is perfect, one of the strangest, most debated mistakes can be found in the scene. Watch as Elsa pulls her braided hair from behind her shoulder to the front - until it magically travels through her shoulder, already in front ahead of time. Don't be surprised if you don't catch it the first time, but trust us, it doesn't add up.

Toy Story

It may be Pixar's first movie mistake, and it's impossible to miss for any parent who's used a baby monitor to keep a close ear on a sleeping baby. When the army men first set out to see what new toys Andy's gotten for his birthday, they're carrying the handheld unit - which only plays audio. They use the monitor as a walkie-talkie, and Woody's base unit should let him send messages, but the actual device wouldn't make much sense if it send sound both ways.

Tangled

When your lead character has hair longer than  a football field, some mistakes are to be expected. But it's obvious the animators wasted no time in deciding what they could and couldn't actually show: the second Rapunzel leaves her tower, her hair ceases to exist. It's understandable, but still a shame since it's impossible to miss on repeat viewings.
