From the Super Mario Wiki
In The Adventures of Super Mario Bros. 3 episode Dadzilla, Big Mouth and Kootie Pie demand for Madzilla to let them play their own private concert in the Hollywood Bowl immediately. Unable to deny their request, Madzilla goes over to the Hollywood Bowl and rips it out of the ground while a man is performing on a piano.
Madzilla then brings the Hollywood Bowl back to Big Mouth and Kootie Pie, and places it around them so that they can perform their own proper concert. Big Mouth and Kootie Pie perform the song Stomp My Name on the Walk of Fame, although the entire crowd hates it and throws everything that they got their hands on at the Koopalings.
