Ultraman Taro: S1 E8 - The Spirit Of The Man-Eating Marsh Ultraman Taro

Attacks by a giant red light have been occurring near a so-called man-eating marsh. ZAT thinks there's a secret to the marsh and launches the Subterrene Pellumidar 2. As Kotaro and Kitajima dig underground aboard the Pellumidar 2, they find the monster Tondaile.
