This is part 29 of my Super Mario Galaxy gameplay walkthrough for the Nintendo Wii! In this part, we do the last Galaxy inside the Engine Room which is the enemy base, Bowser Jr.s Lava Reactor. Bowser Jr. brings back King Kaliente to seek his revenge and his plans are foiled again and we claim our 6th Grand Star. We only have one more place to go before the final battle! ~Enjoy! :]
