The Norimaki Family, the Soramame Family, Suppaman, and Dr. Mashirito end up coming to a summer resort which is really a haunted castle filled with monsters. While enjoying the many facilities, such as the arcades and hot spring baths, they all end up falling into the clutches of Vandora, a female vampire who intends to feed off them.
Unfortunately the movie Dr. Slump and Arale-chan: N-cha!! Excited Heart of Summer Vacation is not yet available on HBO Max.
