There's no business like ghost business and when you join Mystery Inc. you get to travel! Start packing because you're going on an endless spooktacular summer vacation, visiting countries from around the ghostly globe – including Egypt, Greece, Tokyo and Transylvania… even the snowy glaciers of the South Pole! Thank goodness you're not afraid of ghosts...or vampires, mummies, an invisible madman and fire-breathing toy dragons!

The third season features everyone's favorite crime solvers in a number of sports-themed settings. From a wrestling match gone wrong to a haunted stock car race, and even a mini-golf tournament terrorized by a metallic clown, the gang keeps their cool in any arena. But Season Three offers more than just spooky sports events as the globetrotting gang of ghostbusters visits Paris, Moscow, Hong Kong, Australia, and the Old West. Ruh-roh, indeed!
