In Ghosts on the go the gang crosses the Atlantic Ocean and takes on Europe! They attend a Renaissance Fair, where a dragon interrupts their fun. In Greece, an ancient myth apparently comes to life because of a medallion Shaggy is wearing. The gang's Italian vacation is interrupted by misdeeds in the ancient city of Pompeii, leading to an ominous visit into the mouth of the not so dormant Vesuvius. The gang goes to Paris to see Daphne's cousin become a model, but only to discover she's been abducted by a giant gargoyle.

Pompeii & circumstance -- Large dragon at large -- It's all Greek to Scooby-Doo -- Ready to scare.
