Black Hole & White Hole Pen

Synopsis

Reluctant to carry fishing gear to a neighbor, Nobita begs Doraemon for help with the heavy load. Doraemon produces the "Black Hole Pen and White Hole Pen"—based on cosmic phenomena, the black hole pen sucks objects into circles drawn with it, and the white hole pen expels them. Successfully delivering the fishing gear and receiving juice as thanks, Nobita encounters Sneaky being chased by Gian. Using the pens, they help each other—until Nobita carelessly leaves a black hole circle open in Sneaky's room and drops the white hole pen elsewhere. The unsecured circle begins consuming Sneaky's belongings, creating escalating disaster.
