"The player controls Scooby-Doo to defeat enemies, collect clues for Velma and ingredients for Shaggy, and solve the mystery. Scooby-Doo can change costumes in certain areas, which can give him different abilities such as kung-fu, gliding like a bat and archery with plungers. These costumes are necessary in order to complete some levels. In the Nintendo DS version, there are a few minigames included to make use of its touchscreen." wikipedia.org
