Woohoo Hooniversity

WooHoo Hooniversity is a university in the Beanbean Kingdom that was used by Cackletta as a spot to awaken the Beanstar during the events of Mario & Luigi: Superstar Saga.

Cackletta and Fawful overtook the university and turned all of their scientists into Laser Snifits. In fact, Mario and Luigi saw a professor transform right before their eyes. They had to complete many tasks and defeat many of these monsters on their journey through the building. By repositioning a multitude of mirrors, they managed to shine light on, and open the Sun Door, which lead to the room where the villains were preparing to awaken the Beanstar. However, when Cackletta activated the Peach Bots that supposedly housed Princess Peach's stolen voice, they made a strange noise that angered the Beanstar, causing it to destroy the ground beneath it, sending it and the Peach Bots falling down into the university's basement. Mario and Luigi fought and defeated Cackletta, who's essence is sucked up by Fawful (into his headgear) for safe-keeping. Prince Peasley then appears and throws Fawful out of the university, before telling the brothers to go to the basement and retrieve the Beanstar. However, Popple and Rookie (who was actually an amnesiac Bowser) had already found the artifact and had to be defeated in order for the Mario Bros. to obtain ownership of the Beanstar. Unfortunately, a Peach Bot then crashed down and made the horrible sound again, causing the Beanstar to fly up into the air and out of the Woohoo Hooniversity in rage, with Mario, Luigi, Popple, and Rookie in tow. If the player explores enough, they will find a room where item blocks are created and has section with the blocks from the original Super Mario Bros., Super Mario World, Super Mario 64, and Paper Mario.

According to the instruction booklet, here is where the chemistry of laughter is researched.
