The delightful trailer begins with the toys happily holding hands in a circle as the camera pans on each of them by turn with the back drop of a blue sky and white puffy clouds as Joni Mitchell sings Both Sides, Now in the background.
The circle comes to a sudden halt on a distressed looking Forky, who is holding Woody's hand.
He screams: "I don't belong here," and runs off as the toys pile up behind Woody.
"I'm not a spork," the deeply conflicted utensil yells as Woody says, "Hey, hey, somebody get him before he pokes an eye out."
Fans immediately took to social media to share their comments about the trailer, with most being positive.
"It's only Monday, and you have already made our week," said one.
Toy Story 4 director by Josh Cooley said: "Like most people, I assumed that Toy Story 3 was the end of the story. And it was the end of Woody's story with Andy. But just like in life, every ending is a new beginning.
"Woody now being in a new room, with new toys, and a new kid, was something we have never seen before. The questions of what that would be like became the beginning of an entertaining story worth exploring."
Actors Tom Hanks, Tim Allen and Joan Cusack return as the voices of Woody, Buzz and Jessie, and comedian Tony Hale lends his voice to Forky.
New Zealand fans will have to wait until June 27, 2019, to see Toy Story 4.
