Scooby-Doo is a talking dog cartoon character and star of a series of different animated television shows and movies from the Hanna-Barbera company. The premise of the various cartoons is that Scooby, along with his friends Shaggy, Fred, Daphne and Velma, travel to various locations in a van called the Mystery Machine to hunt for ghosts and other monsters. In many situations, the monsters end up being amusement park owners or other regular people dressing up in costumes in an attempt to scare local citizens and complete some form of illicit or nefarious activity.
Many of the Scooby-Doo games follow this premise, allowing the player to control Scooby or one of his friends as they battle monsters and explore seemingly haunted areas. For example, in the game "Scooby Trap," the player takes control of Scooby-Doo as he attempts to outrun different creatures chasing him and avoid various obstacles. Each level of the game contains different traps and enemies, which Scooby needs to avoid in order to proceed.
