Star Wars: The Clone Wars - Season 2 Episode 18 -

The Republic's newest droid-annihilating proton bomb awakens a monstrous, gargantuan and near-invincible beast from its underground hibernation. Mace Windu and Anakin Skywalker face a dilemma: save the beast as the last specimen of its kind, or help the Dugs kill it and secure a treaty for critical fuel supplies? Note: This episode and the creature's name pay homage to the legendary Japanese giant monster Godzilla.
