Weekenders Adventures of Finding Dory is another upcoming sequel to Weekenders Adventures of Finding Nemo created by Sonic876. It will appear on Google Drive in the near future.
One year after reuniting Nemo with his father Marlin, Dory has become a helping hand in raising Nemo. One day during a lesson with Nemo's class, Dory recalls through a childhood flashback that she has a family. She decides to look for them but finds her short-term memory loss to be an obstacle. The only thing she remembers is that they lived at the Jewel of Morro Bay.
Marlin and Nemo accompany Dory in her quest. With the help of Crush, they ride a water current to California. Upon arrival, they are forced to flee from a predatory giant squid that nearly devours Nemo. Marlin tends to his son afterwards and is sour toward Dory for getting them into the mess. Feeling hurt, Dory travels to the surface to seek help and is rescued by staff from the nearby Marine Life Institute after being caught in six pack rings; she is separated from Marlin and Nemo.
Dory is sent to the Quarantine section and tagged. There she meets a grouchy but well-meaning, seven-legged octopus named Hank. Dory's tag shows that she will be sent to a permanent aquarium in Cleveland. Due to a traumatic ocean life, Hank wants to live in the aquarium, so he agrees to help Dory find her parents in exchange for her tag. In one exhibit, Dory encounters her childhood friend Destiny, a nearsighted whale shark who communicated with Dory through pipes, and Bailey, a beluga whale who believes he is unable to echolocate. Dory learns that the rest of her regal blue tangs species are being moved to Cleveland. She subsequently has flashbacks of life with her parents and struggles to recall details.
Marlin and Nemo attempt to rescue Dory. With the help of two sea lions named Fluke and Rudder and a common loon named Becky, they manage to get into the Institute. Dory finally remembers how she became separated from her parents: she overheard her mother crying one night, left home to retrieve a shell in hopes of cheering her up, and was pulled away by an undertow current.
Dory reunites with Marlin and Nemo in the pipe system. Back in Quarantine, they locate the tank of blue tangs, who tell her that her parents escaped the Institute to search for Dory but never came back. Dory realizes her parents are likely dead. Hank retrieves Dory from the tank, accidentally leaving Marlin and Nemo behind. He is then apprehended by one of the employees and accidentally drops Dory into the drain flushing her to the ocean. Dory comes across a trail of shells, remembering that when she was young, her parents had set out a similar trail to teach her how to find her way back home. At the end of the trail, Dory finds an empty home with multiple shell trails leading away from it. As she turns to leave, she sees her parents, Charlie and Jenny, in the distance and joyfully reunites with them. They tell her they have spent years forming trails for her to follow in the hopes that she would eventually find them.
Marlin and Nemo end up in the truck taking various aquatic life to Cleveland. Destiny and Bailey help Dory rescue them. Once aboard the truck, Dory persuades Hank to come back to the ocean with her, and together they hijack the truck, crash it into the water, and free all the fish. Dory, along with her parents and newfound friends, return to the reef with Marlin and Nemo.
In a post-credits scene, the Tank Gang from the first film, still trapped in algae-covered plastic bags, reach California a year after floating across the Pacific. They are promptly rescued by volunteers.
