Ghoul Patrol

Ghoul Patrol stars Zeke and Julie, the coolest ghoul-tracking teenagers around. Gamers must battle oddball opponents like skeletons in shining armor, and learn about good, bad, and "random" potions. Packed with a zany scenarios from a Ming garden to a pirate ship, Ghoul Patrol allows cooperative two-player action.
