where they then become a form of outside advertising. Drinks A hallmark of tiki bars are specialty drinks, some of which may be unique to a bar and the recipes for which were often carefully guarded in order to prevent imitation from competing bars or from customers trying to recreate a drink at home. Multiple types of rums (light, dark, spiced, overproof and originating from various countries) are typically mixed together with orange liqueurs (Triple sec, Grand Marnier, Cointreau), tropical fruit juices, sweet syrups (falernum, fassionola, orgeat) and bitters. Many are bright in color, including more unusual cocktail colors such as blue (from Curaçao) and green hues (from Midori or Crème de menthe). Some classic drink recipes from the early tiki era, many attributed to Don the Beachcomber or Trader Vic, include the: Blue Hawaii, Cobra's Fang, Coffee Grog, Corpse Reviver, Doctor Funk, Diki-Diki, Fog Cutter, Fu Manchu, Gold Cup, Head Hunter, Mai Tai, Navy Grog, Lapu Lapu, Mr. Bali Hai, Outrigger, Pago Pago, Pearl Diver, Py Yi, Planter's Punch, QB Cooler, Rum Barrel, Scorpion, Shark's Tooth, Shrunken Head, Singapore Sling, Suffering Bastard, Sumatra Kula, Test Pilot, Three Dots & A Dash, and the Zombie New tiki drinks continue to be created by a variety of bartenders and others. Jeff "Beachbum" Berry devised two cocktails in honor of new-wave tiki-pioneers Sven Kirsten and Otto Von Stroheim, with the Sven-Tiki and Otto's Grotto cocktails. He is also known from having created the Ancient Mariner and Von Tiki cocktails. Beyond fruit, cocktails are often garnished for customers with paper cocktail umbrellas, fancy swizzle sticks, live flowers or plastic animals. Cocktails can be very complicated and dramatic, often served in decorated ceramic vessels, employing dry ice or ice shells, or may be set on fire. The ordering of some drinks also triggers a serving ritual, such as the Mystery Drink that could result in the ringing of a gong and a hula dressed "mystery girl" bringing the beverage to the table; the mystery drink was once popular enough that Johnny Carson "ordered" it twice during the filming of The Tonight Show. Some drinks ordered at Disney's Enchanted Tiki Bar also result in certain things happening, such as the ordering of a Krakatoa Punch causing the picture of a faux volcano to erupt. Tiki mugs and drink vessels As the term is used generically, "tiki mugs" are ceramic drink vessels traditionally shaped as tikis,
