Ludwig's Castle

Ludwig's  Castle is the final level of the Twin Bridges and can be accessed by Butter Bridge Arena or Cookie Mountain. This level contains an ON/OFF Switch to help you get through the second section. The final section is a lot like the one at Iggy's Castle. However, the only difference is it goes completely vertical. The Boss Door leads to Ludwig von Koopa. After his defeat, the fourth Yoshi Egg is saved and Mario attempts to blow up the castle. However, the detonation forces the castle to rocket into the air and crash into the nearby hill. The hill gets a bandage after this and you get to go to the fifth world, Forest of Illusion.
