Disney's Adventures of the Gummi Bears S02 E06 The Crimson Avenger

When Cubbi claims he is serious about Calla's knighthood from "Up, Up & Away", the annoyed Gummis suggest he go into the forest to be a hero. After saving some people, Cubbi gets the reputation as "the Crimson Avenger". Although Cubbi has done a good job by protecting people from a highwayman trying to rob them, the thief elects to move into Dunwyn Castle - along with chances for juicier crimes, which end up causing problems for Calla, Cavin and King Gregor.
