From TikiLand Trading Company:

"This siren and her giant seahorse roam the seas, but no one knows exactly why. For hundreds of years sailors and seafaring folk have claimed to have seen these magnificent creatures. Endless rumors persist, but the most common is that the pair lure you to the depths of a tasty libation. This ceramic tiki mug is about 8 inches tall, and holds about 19oz.
