the fictional worlds of children's toys, sentient cars, and culinary rodents,

it didn't take long for fans to realize that these stories aren't as separate as they thought.

Fans have spun wild theories on a single unified "Pixar Universe", blurring the lines between

Pixar's superheroes, animals, toys, and everyday people. One overall story may be

impossible to find, but hunting down each Easter egg is more than worth the effort.

Here are Screen Rant's 10 Amazing Hidden Details In Disney Films Part 2.

The Illustrated Bug's Life

A Bug's Life was one of Pixar's earliest films following Toy Story's success, the story of one

insect's pursuit of a great adventure has proven just as worthy of Easter eggs, and hidden nods throughout Pixar's talented team.

As proof that the film is still worthy of attention,

a scene in Toy Story 2 shows even Mrs. Potato Head is a fan, as she reads an illustrated version of A Bug's Life's story.

Is it merely a nod to an underrated film, or explicit confirmation

that A Bug's Life is a work of fiction to Andy and his toys…?

Bugs & Monsters

There's no doubt that the fantastical adventure based on the monsters that keep children up

at night caught more attention than A Bug's Life, but the two are directly linked.

A good chunk of the insect adventure is set in the shadow of a mobile home, parked alongside

the infamous Pizza Planet delivery truck – which is one of Pixar's signature Easter eggs,

appearing in nearly every one of their films. When the villain of Monsters, Inc., Randall is sent

into the home as punishment, he's forced to deal with its gator-hating inhabitants.

Monsters, Inc. doesn't miss out on its own nod to the movie that started it all, either.

Where's Woody?

When Sulley returns the mischievous Boo to her very own bedroom at the end of the first Monsters adventure,

she isn't ready to leave, showing off her toy collection to what she

thinks is her big blue "kitty". The "Luxo Ball" from Pixar's earliest animated shorts

can be seen, but Boo takes particular pride in her cowgirl Jessie doll, well-known to fans of Toy Story 2,

and apparently a hit with more kids than just Andy.

Buzz Down Under

For a movie based in the oceans, Finding Nemo hints at more connections to Pixar's other

properties than you would expect. When the wayward Nemo finds himself living in a dentist

office aquarium, viewers are given more than a few glimpses of the waiting room and its

sometimes terrifying patients. Among the toys scattered around for children to play with

is the unmistakable profile of Buzz Lightyear, one star of the Toy Story series that was

apparently even popular in Australia.

One Incredible Comic

The Toy Story movies always implied that there were thousands of each toy scattered around

the world, but another nod in Finding Nemo isn't so easily explained. A young boy can

later be seen reading a comic book in the dentist's office waiting room clearly showing

a young Mr. Incredible on its cover. Whether it's a real adventure from the golden age

of Pixar superheroes, or a sign that The Incredibles are merely comic book characters in Pixar's universe,

that's for fans to decide.

Car People

It may not be the most critically-acclaimed of Pixar's movies, but the commercial power

of Cars made it an overnight sensation – and the wealth of Easter eggs spread across the studio's other movies,

shows the designers have a soft spot for the story of humanized vehicles.

Although the world of Cars is lacking human beings, the characters of the Toy Story

series are clearly fans: the third film in the series includes a simplified version of the

star, Lightning McQueen, and a child wearing a t-shirt boasting his logo and number.

Even Andy is a fan, with a calendar in his room showing a more realistic version of the

sneezy Snot Rod.

Jurassic Gas

As an added bonus, the gas company, Dinoco, seen to sponsor the film's famous Piston Cup,

is also a gas company in the world of Toy Story. And if viewers look close enough,

the unmistakable dinosaur on the company's logo can be seen spotted on a lighter in Wall-E's

collection of human artifacts.

Incredible Underwear

The story of a runaway rat with a flair for high-end cooking may not seem to have little in

common with Pixar's other releases, but it turns out comic book superheroes are just

as popular in the film's version of Paris as they are in the real one. This is clearly evidenced

by the "Incredibles" logo on Linguini's underwear.

A Telltale Shadow

The timeline of the Pixar universe is also played within Ratatouille, as Remy's

adventures through Paris end up bringing him dangerously close to an unseen dog.

But a closer look at the dog's shadow reveals it to be not other than Dug, the fan-favorite

canine from Pixar's Up, he appears here years before his own movie hit theaters – and

apparently before a groundbreaking collar allowed him to speak English.

Wall-E

As light-hearted and hopeful as Pixar's movies tend to be, Wall-E showed that if every

story is set in the same fictional world, then all are headed for a seriously depressing end.

Wall-E has set decades in the future, and shows a single sanitation robot charged with cleaning

up the Earth after it's been turned into one massive landfill.

One big box retailer, Buy n Large is to blame for the mess, with their corporate logo spread throughout the movie.

The BnL logo is shown on Buzz Lightyear's batteries in Toy Story 3. Leaving no doubt that all of Pixar's humans are headed for this fate.

But at least the humans got to escape Earth. Toy Story's Rex wasn't so lucky,

he can also be spotted in Wall-E's collection.
