Aloha Palooza is a stadium seen in Leroy & Stitch. It is where the first 624 of Jumba's experiments are rounded up by Leroy and taken to be destroyed. Shortly after, Hämsterviel and the entire Leroy army arrive at the stadium on Earth in the BRB to destroy the captured experiments. Before they could, however, Lilo, Stitch, Jumba, Pleakley, Reuben and a reformed Gantu arrive and a battle ensues between the experiments and the Leroys. Though the experiments were able to overpower the Leroys at first, the Leroys soon gained the upper hand.
However, as the Leroys came close to winning the battle, Lilo, Stitch, Reuben and several other experiments performed the song "Aloha `Oe," which caused all the Leroys to shut down due to the original's fail-safe. The experiments then leave the stadium and go back to their one true place where they belong.
The stadium greatly resembles the real-life Aloha Stadium located in Halawa, Hawaii (a western suburb of Honolulu). It could also be that the stadium is actually Aloha Stadium itself, and the "Aloha Palooza" sign hung outside is actually referring to an event that was going to be held there.
