Danger Mouse is the quick-witted white mouse at the center of a British animated spy comedy, parodying the daring secret-agent hero. His missions bring him together with timid hamster sidekick Penfold and superior Colonel K, and into conflict with the scheming toad Baron Greenback and his henchman Stiletto. The character collection reflects that mix of hero, allies, adversaries, and action, with examples including Danger Mouse in motion and with his car, as well as Baron Greenback with Nero, his fluffy caterpillar companion.
