Anakin and Obi-Wan’s Unknown MONSTER FIGHT on Mustafar in Revenge of the Sith – Star Wars Theory

How Anakin and Obi-Wan Kenobi were supposed to fight this massive monster creature on Mustafar in Star Wars Revenge of the Sith…it was a concept that even was supposed to be in the game, however, it didn’t happen! I think we could have gotten 2 scenarios from this, and it would have definitely been cool to see. What do you think? Ruins the tempo? Or adds to the story??
