Plot
Rikit (dressed as Doraemon) was getting ready for Halloween while Jacaro (dressed as Nobita) was getting the bags for trick-or-treat. They were walking through the neighbourhood looking for treats and play tricks when Mikit (dressed as Dorami) flew towards them, saying that all of the treats have been stolen on Mischief Night. Rikit and Jacaro at first didn't believe her but Mikit show a video of many sweets being stolen which made Rikit and Jacaro want to find who stole them. They looked all around the neighbourhood until they found an abandoned house which Rikit at first refused to go into but later agreed when Jacaro wants to go in the house. They looked around the house until they found the sweets laying on the ground but they were protected by the ghost of Hideki Tojo who has been stealing all of the sweets from the houses. Rikit, Mikit and Jacaro wanted to confront him but they were scared of what he might do so they decided to play a trick on him by leading him away from the sweets and vacuuming him while he was distracted. The sweets were saved but when Jacaro was about to wish for the sweets to return to their rightful owners, a bunch of ghosts appeared in front of them and revealed that they helped Hideki steal all of the sweets but could never eat them due to being ghosts but Jacaro, Rikit and Mikit told them that this whole experience taught them that Halloween is not all about sweets so Jacaro wished the sweets back to their rightful owners, which Rikit and Mikit both did, and they waved goodbye to the ghosts, hoping to visit them again, while Mikit says that she has to return to Hiroshi and Mokono in heaven, which she did, and Rikit and Jacaro went back home and never told Jacaro's parents about what happened.
