Madzilla

Madzilla is a fictional monster who stars in movies in the Real World. In the Episode Dadzilla, Kootie Pie and Big Mouth think that Madzilla is their real father, so they use their Magic Scepters to bring a mechanical Madzilla to life. Kootie Pie and Big Mouth fool Madzilla into thinking that they are his long lost children, and tell him what parents are "supposed" to do. At first, Madzilla was not evil, and only wishes the best for his "children". Eventually, Mario and the group catch on to the two Koopalings plans, and come to stop it. However, Madzilla locks them up in a Movie Studio. They then build their own Robot to play the role of Madzilla's mother. They use this against the Koopalings by making the Robot tell the two Koopalings to do Choirs and take Naps, etc. Kootie Pie and Big Mouth then run back to the Mushroom Kingdom, and back to Bowser, as they do not like this new family. After this, Mario, Luigi, Princess Toadstool, and Toad explain everything to Madzilla, and allow him to live in Giant Land, to which he happily accepts, especially once he finds out that the Koopa Kids will no longer bother him! It is presumed that he still lives in Giant Land.
