Well of Doubt is the one hundred twenty ninth episode of ThunderCats (original series).
Later Lion-O sends Torr, Baron Tass and Mr. Grubber to get water, but on the way the Baron stops at the Well of Doubt and gets some of its water. The water causes a person to become very doubtful of his own abilities. When they get back to the Thundercats, Baron Tass gives some of the water to Lion-O. On the way to inspecting the new Tower in the Whisker, Lion-O feels the effects of the water and causes the Whisker to crash.
Tass comes back (from getting his Guardsman, giant stone-men), and has them attack the Thundercats. Once discovered by Jaguara, Jaguara helps Lion-O overcome his doubts and defeat Baron Tass and Mr. Grubber, who promise to reform.
