Description: The show involved a teenage boy named Mark who fell into the top hat of Merlo the Magician, following Merlo's show at Six Flags Over Texas. Inside the hat, he arrived in Lidsville, a land of living hats that are depicted as having the same characteristics as the humans who would normally wear them. For example, a cowboy hat would act and speak like a cowboy. The characters' houses were also hat-shaped.
