Plot
Nobita throws a temper tantrum as he wants a large RC toy robot in order to upstage the rich friend Suneo, who has been showing off the new robot that his cousin made. His fit makes Doraemon angry and he uses his Anywhere Door to get anyway from the summer heat cool off at the North Pole. Sometime later, Nobita follows and a discovers a strange bowling ball-like orb which starts blinking with a pulsating light, and summons what looks like a giant robot's foot. After Nobita uses the foot to sled down, crashing into his room through the Anywhere Door, the bowling ball follows him home through the door and another robot piece falls into his backyard.
Doraemon follows soon after and admits that he has nothing to do with the robot parts, as the two use the Opposite World Entrance Oil and the Roll-Up Fishing Hole to enter the World Inside the Mirror, an alternate mirror world without people. There, they built the robot which Nobita christens the name "Zanda Claus" as he believed the sphere summoning the parts is from Santa Claus. Using a brain wave controller that Doraemon pulls out of his pocket, Nobita has the robot perform gymnastic maneuvers in a mirror world before bringing Shizuka to join the fun. The trio enjoy with Zanda Claus. However, Shizuka accidentally presses a button on the control panel that makes the robot fire a huge laser beam that destroys a whole skyscraper.
The group realizes just how dangerous Zanda Claus really is, and they decide to return to the real world and forget about ever having found the robot. However, Nobita forgot about the sphere that has been sending telepathic messages to a mysterious girl named Riruru. The actual owner of Zanda Claus, Riruru seeks out Nobita when he accidentally lets slip all that he knows about the robot. After Riruru proceeds to force him into showing her where it is, Nobita borrows the Roll-Up Fishing Hole from the spare pocket Doraemon keeps in the closet to take her to the World Inside the Mirror. She reclaims Zanda Claus while getting Nobita to let her borrow the Roll-Up Fishing Hole for a while. After some time, Nobita is visibly nervous about what she is up to and, after seeing two shooting stars in a row, he uses the Bamboo Copter to investigate the forest at Mt. Ura.
Nobita follows another shooting star through the unrolled Roll-Up Fishing Hole and finds Riruru building a massive robot army. Doraemon, having been suspicious of Nobita's peculiar behavior at home, follows him there. They enter the mirror world and see a massive base being built by humanoid robots. The duo then use a long-range Paper Cup Phone to listen in on Riruru as she orders the robots to work faster. She is revealed to be a human-hating robot. When Riruru discovers them, Nobita and Doraemon escape to their own world with the portal accidentally destroyed by Zanda Claus, but the two have completely forgotten about the sphere that is still at home, before it suddenly wakes out and bounces around. After Doraemon puts Translation Jelly, the sphere introduces itself as the 'brain' of Zanda Claus, while alerting him about a giant robot army that intends to conquer Earth and enslave all humanity. They try to alert the authorities but in vain as none of them believes Doraemon or Nobita.
