Winnie the Pooh vs. Gremlins is another Winnie the Pooh/Steven Spielberg Crossover film to be created by Daniel Esposito and Joshua Smith. It will appear on Dropbox as part of a double feature with its sequel Winnie the Pooh vs. Gremlins 2: The New Batch in the near future.
Randall Peltzer, a struggling inventor, visits a Chinatown antique store in the hope to find a Christmas present for his son Billy. In the store, Randall encounters a small, furry creature called a mogwai (Cantonese: 魔怪, "monster"). The owner Mr. Wing refuses to sell the creature to Randall, though his grandson secretly sells the mogwai to Randall but tells him to remember three important rules that must never be broken – do not expose the mogwai to bright lights or sunlight which will kill it, do not let it get wet, and never feed it after midnight.
Randall returns home to Kingston Falls where he gives the mogwai to Billy as a pet. Billy works in the local bank, and fears his dog Barney will be put down by Mrs. Deagle. Randall names the mogwai “Gizmo” and Billy makes sure to treat him well. But when Billy’s friend Pete spills a glass of water over Gizmo, five more mogwai spawn from his back, a more troublemaking sort led by the aggressive Stripe. Billy shows one of the mogwai to his former science teacher Mr. Hanson, spawning another mogwai, who Hanson experiments on. Stripe’s gang trick Billy into feeding them after midnight by chewing out the power cord to his bedside clock and transform into cocoons, as does Hanson’s mogwai. Shortly after, their cocoons hatch and they emerge as mischievous, reptilian Gremlins that torture Gizmo and try to murder Billy’s mother, while Hanson is killed by his Gremlin.
All of the Gremlins are killed except Stripe, who escapes to a local YMCA and jumps into a swimming pool, spawning an army of Gremlins who wreak massive chaos around Kingston Falls. Billy tries to warn the police but they don’t believe him. Many people are injured or outright killed by the Gremlins’ rampage, including Mrs. Deagle, who is launched out of her house on a stair lift that has been sabotaged by the gremlins. At the local bar, the Gremlins have fun until the barmaid Kate Beringer, Billy’s girlfriend, flashes them with a camera and escapes into the bank with Billy and Gizmo. While hiding, she reveals her father died in a chimney while dressed as Santa Claus. Billy and Kate discover the town has fallen silent and the Gremlins are watching Snow White and the Seven Dwarfs in a theater. They set off an explosion, killing all the Gremlins except Stripe.
Billy chases Stripe into a Montgomery Ward store, where Stripe climbs into a water fountain and tries to spawn more Gremlins. Gizmo arrives in a toy car and opens a skylight, exposing Stripe to extreme sunlight and melting him. In the aftermath of the Gremlins’ rampage, Mr. Wing arrives to collect Gizmo, scolding the Peltzers for their carelessness, thinking the Western world is not ready but comments that Billy might some day be ready to care for Gizmo properly. Gizmo likewise believes so, having become attached to Billy. Mr. Wing departs with Gizmo in tow, while Randall narrates to the audience to check their house if things go wrong, because "there just might be a Gremlin in your house".
