Kelsey Grammer reprises his role as the guest voice of Sideshow Bob, and the opening musical sequence was animated by John Kricfalusi.

The episode opens with a John Kricfalusi–animated couch gag where the Simpson children are trick-or-treating before being set upon by soul-hungry spirits with a monstrous Frank Grimes among them that skins Bart for his soul before Maggie saves him and Lisa.

As his main objective in life is done, he decides to complete other dreams, such as becoming a literature teacher at Springfield University, but is dissatisfied as his students are lazy cheaters.

Bart puts Bob's head into the Reanimator with a horn, frog legs, a chicken body, a tail and a booger, making a bizarre-looking creature.

In a parody of Godzilla and the 1998 version, a crazy old Japanese man based on Grampa Simpson is constantly mocked because every day he drops a perfect donut into the ocean.

The scene cuts to the present time, where executives are watching the black-and-white Homerzilla film, stating that it is so bad that it deserves a remake.

They throw all the merchandising into the ocean, but the containers wake up the real Homerzilla and a message appears reporting that he will return as soon as people have forgotten about the last film.

Bart scares Lisa with dead owls, and she hits Milhouse's nose with the camera, making him lose his balance and fall into a giant hole.

Bart and Lisa decide to jump into the hole to rescue him, making all the three stuck inside of it with nuclear waste from the power plant.

Maggie then uses her powers to benefit the world, such as turning Homerzilla into a larger Barney the Dinosaur before taking a nap while still floating in the air.

"[4] He was more favoring towards the satire in "Homerzilla", but concluded that it had "not too much meat on [its] bones", and decried the lack of originality in the final segment, although he approved of Principal Skinner correcting graffiti to call himself a "wiener".

He stated that the episode was "fun and has its share of laughs, but doesn’t raise the dead or leave a dent in the family car.

"[7] Colin Piwtorak of The Daily of the University of Washington thought the episode was "lazy and uncreative" and stated that the best part was the segment by John Kricfalusi.
