Subtitles section Play video Print subtitles Pixar is famous for dropping Easter eggs throughout their films, and the Toy Story franchise's fourth installment is full of tiny details only the most eagle-eyed viewers will catch. Here's a list of things you probably missed in Toy Story 4. Toy Story 4 starts with a flashback to nine years earlier, where Woody and Bo Peep are conducting a rescue mission to save Andy's remote control toy car, RC, from being swept away in a rainstorm. Luckily, the team is able to save RC just as a real car pulls into the Davis' driveway. This crucial scene reveals where in the world Bo Peep was in Toy Story 3, because the person driving the car is there to take her away. If tears aren't clouding your eyes, you may be able to make out the letters and numbers on the car's license plate: RMR F97. In a 2019 press conference, producer Mark Nielsen revealed that those letters and digits were fully intentional. Saying:"On Toy Story 2, there was someone who worked on the show that accidentally deleted the movie from the render farm. "That was the command on the computer that deleted the film." Producer Jonas Rivera added:"It felt appropriate that the license plate on the car that takes Bo away would be the same that killed Toy Story 2." Randy Newman's cheery song, "You've Got a Friend In Me," was the theme song for the very first Toy Story movie, and has since been used in each of its sequels. The famous song made a welcome comeback with Toy Story 4, but the film also graced fans with two brand spanking new Randy Newman tunes. The first of said tunes, "I Can't Let You Throw Yourself Away," can be heard during the montage of Woody quite literally not letting Forky throw himself away. "You're Bonnie's toy." "You are going to help create happy memories that will last for the rest of her life." "Huh, what?" "Oh, ah, ugh!" A more appropriate song title has never existed. As Newman explained: "Forky gets it in his head that he's disposable, so he keeps trying to throw himself in the trash can, and Woody has put himself in charge of keeping him from doing so." The second of the singer-songwriter's new original songs is the backing track for the film's end credits — though Newman gave his voice a break for this one. Instead, country crooner Chris Stapleton lent his vocal talent to the Western-inspired tune, titled, "The Ballad of the Lonesome Cowboy." Though fans had long speculated that Pixar films were all connected in some way, writer Jon Negroni popularized the idea with a viral 2013 blog post titled "The Pixar Theory." In his post, Negroni put forth the idea that Boo — the adorable little girl from Monsters, Inc. — is actually the witch from Brave. You know, the witch who transformed Brave's villain Mordu from a prince to a bear. As Negroni explained: "She probably wanted to turn him into a bear because Sulley resembles a bear, and she is still trying to figure out where Sulley comes from." As outlandish as it may sound, there seem to be a couple of Easter eggs hidden throughout Toy Story 4 that will make the hearts of Pixar Theory believers soar. During Bonnie's first day of Kindergarten, an out-of-focus Boo seemingly sits just a few tables away. But the more obvious egg comes in the form of Bunny, one of the stuffed prizes Buzz meets at the carnival. As Entertainment Weekly notes, the fuzzy, floppy-eared, blue-and-green Bunny bears a striking resemblance to Sulley the monster. Here's hoping Boo's family makes a trip to the carnival! When Toy Story 3 was released in June 2010, fans were appalled to see Bo Peep, as well as her beloved sheep, Billy, Goat, and Gruff, had seemingly been erased. Fortunately, the fourth installment of the franchise made it up to fans in a major way by putting Bo and her journey to be more than just a toy collecting dust on a shelf front-and-center. "Woody, who needs a kid's room when you can have all of this?" In a press conference, director Josh Cooley revealed: "Having Bo come back was the genesis of this film. We even called the movie 'Peep," which was our code name." The fan favorite's return was announced in January 2019. With a short video of Bo startling Buzz and Woody by bursting through a wall behind them, wielding her trademark crook. However, much to the surprise of fans, her signature pink dress and bonnet were nowhere to be found. Instead, the new-and-improved Bo sports a baby-blue jumpsuit with ruffled accents and cap sleeves, along with a pink sash tied around her waist. If you found yourself wishing you, too, could sport Bo's new look — we have good news. ShopDisney.com has the entire look available for just $168. Check out one of our newest videos right here!
