Woohoo Hooniversity

Woohoo Hooniversity is a university in the Beanbean Kingdom that appears in Mario & Luigi: Superstar Saga and its 3DS remake, Mario & Luigi: Superstar Saga + Bowser's Minions, dedicated to the study of laughter. In-game, it is an abandoned, destroyed building with no one but the transformed enemies, and Cackletta and Fawful, when the Mario Bros. arrive, looking for the Beanstar.

History
Cackletta and Fawful take over the university and transform many of its scientists into Laser Snifits. Mario and Luigi soon arrive to stop Cackletta after Prince Peasley mentions that she is there. Once there, they find that Cackletta has locked herself behind a door opened only by light. By positioning certain mirrors, they reroute a beam of light to open the door. When Cackletta activates the Peach-bots that are supposed to contain Princess Peach's voice, however they enrage the Beanstar, crashing it into the university's basement (this is because the voice they stole was actually Birdo's voice). Mario and Luigi arrive shortly after this happens, and Luigi drives Fawful into the ground using his hammer.

Mario and Luigi fight and defeat Cackletta, though with Fawful's help, she lives on as a spirit inside his Headgear. Before they finish off the brothers, however, Prince Peasley appears and knocks them out of the university and into Stardust Fields. The brothers promptly go to the basement of the university to collect the Beanstar. However, Popple and Rookie find it first, and prevent them from collecting it. After Popple and Rookie are defeated, a Peach-bot falls down and emits the voice again, causing the Beanstar to fly up into the air and out of Woohoo Hooniversity in rage, with Mario, Luigi, Popple, and Rookie in tow. They all fall off the Beanstar (with Mario and Luigi landing in Oho Oasis, Popple presumably landing in Chucklehuck Woods and Rookie, who remembers who he really is, Bowser, landing in Stardust Fields) before it explodes into four pieces.
