The New Year's Party in the Wallpaper

On New Year's Day, Nobita wants to have a New Year's party at home, but his mother refuses, saying the house is too small. Doraemon then takes out a wallpaper and sticks it on the wall, revealing a playroom. Nobita invites everyone to play. While playing, they run out of snacks, and Nobita can't ask his mother for any. Doraemon then takes out a wallpaper from a store. Because they run out of soy sauce, Mom asks Nobita to buy some, but he catches Gian in the door and beats him up. Suneo needs to use the toilet, but his mother's position allows her to see it. Doraemon then takes out toilet wallpaper. Since there is no other place to put it, they stick it on the door. Just then, his mother hears the noise upstairs, pushes open the door, knocks the wallpaper off, and Suneo pees in his mouth. Everyone is supposed to leave, but his mother starts making a phone call that won't end for several hours. Doraemon then takes out a wallpaper with a drain hole, showing everyone how to leave using the drain.
