From the rules:
"Creepy things are happening at Eerie Castle!
The distinguished Count Gregorius of Eerie Castle has invited the little vampires to a big feast and is serving lush cherry tomatoes with freshly squeezed juice from blood oranges. However the garlic vampires miss their very favorite garlic dish. They are the only vampires in the whole world who like garlic more than anything else! How on earth could the
Count of Eerie Castle have forgotten the garlic?!
Each player is secretly assigned a vampire. On the way to the castle the vampires have to think carefully about how to move in order to avoid receiving tomatoes (=minus points) rather than their beloved garlic (=plus points). As the vampires don't know which color belongs to whom things can get quite thrilling on the way. The aim of the game is to have collected the most garlic thus having the most points."
