Disney's Adventures of the Gummi Bears - Season 6 Episode 11 True Gritty

Cubbi accidentally wrecks Ursalia's water reservoir, leaving the ancient metropolis short of its most important commodity. While Gruffi, Ursa and Sir Thornberry keep bickering whilst following an ancient aqueduct to find out why the water flow has stopped, Gritty and Cubbi try to lasso and train a few ramas (an amalgam of ram and lama) to fetch water from the not-so-nearest river. But then Gritty tries to get revenge on a group of mountain shepherds for human crimes against the ancient Gummi Bears, and Cubbi has a hard time trying to persuade him otherwise.
