Woohoo Hooniversity

In Mario and Luigi's adventures, they stumble upon the Woohoo Hooniversity in hoping to find their Beanstar. Instead, they find lots of wrong experiments and a guest appearance from Fawful and his master Cackletta. This place has very nice looking rooms and a lot of technology-type of stuff. It is easy to get lost so they install maps in every hallway. The main room is the Sun Door Lock that has a code to be broken which leads our heroes to Cackletta.

After Sun Door Lock
After you unlock the Sun Door Lock, a beam of light will come and open a door. You will have to do many tasks to unlock the other beams of light. After that, you will be able to open the door that leads to the room before Cackletta. Save before you enter the next room because you will fight Cackletta there.
