The Adventures of Teddy Ruxpin - 1x40 - The Hard to Find City- Followmy.tv

Teddy shows Gimmick and Grubby the wonders of the technology the Hermit has shown him, including a cave with a secret door, opened by one of the Crystals. The door reveals a staircase that leads to the Hard To Find City. The Trio revisits the Pavilion, and discover that the pedestal the Crystals were found in also has a space for the Seventh Crystal.
Meanwhile, the Eclipse is raised from the bottom of Leekee Lake, and Tweeg declares war on the Gutangs. LB lets Quellor out of the dungeon to alert the Gutangs of the impending attack. Quellor challenges Tweeg to use the power of the Black Box, and Tweeg (ever the master villain) triggers the device, and erases his own memory, leaving him with oatmeal for brains. The Gutangs pursue the Trio, who escape back down the tunnel, as Tweeg wanders off.
