A Night Louse at the White House is the ninth episode of The New Scooby-Doo Mysteries.


Velma, a research assistant for NASA, brings Daphne, Shaggy and the dogs out to dinner at the White House where they are discussing the new space station Velma helped with. To everyone's surprise, the ghost of George Washington comes, and says he wants to reclaim his home. With that come a few more presidential ghosts, a brass eagle, and paintings that are missing, and others with their eyes cut out. Why are these ghosts haunting the White House?


Part 1

During dinner at the White House, Velma is interviewed about NASA by a news reporter Jessica Byline. But Shaggy and Scooby make faces at the camera. Then, Jessica interviews the Ambassador of Klopstokia, who is interested in the new space program, but his wife is more interested in tea. Then, Jessica interviews Senator Bullhorn, who along with his wife, is rather against the space program. But then, when the President was about to make an announcement to the people about the space program, the Ghost of George Washington appears. The crowd runs away in a panic, but Shaggy and Scooby give him the slip in a room of statues. Meanwhile, Scrappy, Daphne and Velma find a small, brass eagle, their first clue. But when the people try to catch the ghost, they get Scooby by mistake and accuse him.

Meanwhile, Scooby's parents, Mumsy-Doo and Dada-Doo, hear about this on the news. So they pack up to go to Washington D.C. and help him. Mumsy-Doo makes sure to bring Scooby's galoshes.

Back at the White House, the President explains that he knows they weren't responsible for what happened and agreed to let them go if they helped catch the real culprit. The gang follows Marilyn Maxie for their investigation. During this, she explains that the brass eagle is a bedknob to one of the beds in the guest room. So the gang decide to search the rooms to see which one is missing a knob. Shaggy, Scooby and Daphne, disguised as room maids, search the knobs in the Ambassador and his wife's room, but found nothing. Scrappy and Velma, disguised as pest control people search the bed in Senator Bullhorn's room, but still nothing. Then, Shaggy and Scooby encounter an arm coming from a painting on the way to check out Marilyn Maxie's room, which use to belong to President Ulysses S. Grant. But Grant's ghost appeared in the door. The gang run in the other direction, but run into the Ghost of Theodore Roosevelt. After escaping into the room and barricading the door, Daphne finds a brass eagle that fits on the bed. But when they put it on, a trap door leads them into a secret passage.

Part 2

After Shaggy, Scooby and Daphne fall through a hole in the floor, they grab the wooden board debris. Then, Velma and Scrappy come to the rescue and pull them up. Soon, the gang find a room filled with painted portraits of the Presidents. They had been removed from their frames and replaced with the ones with the eye-holes upstairs. When Shaggy finds the portrait of Abraham Lincoln, Scooby briefly imitates him. But Lincoln's ghost appears and chases the gang away. After the gang gets back up to the White House ground floor, they decide it's time to wrap up the mystery. After getting the President, his wife, the Ambassador and his wife and Mr. and Mrs. Bullhorn, the gang concluded that whoever was dressing up as the ghosts was trying to steal the realPresidents' portraits and make off with them. They knew it had to be someone who had access all of the rooms in the White House, Marilyn Maxie.

But, the mystery wasn't over yet. Suddenly, Washington's ghost reappeared and stole a brass eagle from the President's room. The eagle fits on a flag pole, which opens the secret hiding place of the NASA computers. Washington went through the passage and came out stealing a computer tape. The gang chased him up to the roof, where 'ghost' Lincoln was waiting for Washington with a helicopter. The two ghosts took off, but left some of the computer tape caught dangling out the door. Shaggy and Scooby got caught on the helicopter, so Scrappy, the President, Daphne and Velma all took another chopper to chase the ghosts. But then, the dangling computer tape wrapped around the Washington Monument, causing it to crash. Jessica and her cameraman followed the action as the gang chased after the ghosts. When suddenly, Mumsy-Doo and Dada-Doo flew over them in another helicopter. Mumsy-Doo tried to drop Scooby's galoshes to him, but they landed on Lincoln and Washington's heads, making them fall into the water. The ghosts were really the ambassador and his wife, who were spies trying to steal secrets about the American space program.
