Scooby Doo and his friends have teamed up as the famous Mysteri Inc. team to investigate suspicious activity. This time, their adventures are dangerous because a mysterious news has shaken the world: A spacecraft bound for Mercury had disappeared and no trace of the astronauts aboard could be found, so they needed a spacecraft to reach the planet. Researchers at NASA noted that the surface of Mercury is dangerous and challenging. They also said that a specialized spacecraft was needed to land on Mercury and that the equipment had to be rigorously inspected. But Scooby Doo and his friends were brave characters who feared no danger and decided to take on the mission. A converted spacecraft from The Mystery Machine was specially built for them.
