Marvin the Martian pays a visit to the babies, but no one likes him so Taz befriends Marvin to make him feel welcome. Then everyone else feels the same.
The babies dress up for Halloween, while Lola, Melissa, and Petunia end up with ridiculous costumes. Three Martian Birds accompany them on their trick or treating while Sylvester braves Hilltop Manor. The three girls win in the costume contest for originality.
Floyd take the babies to Auntie’s Bakery, where they love cinnamon rolls, but unfortunately the bakery’s business is due to close down. Everyone works hard to get the bakery in the book of world records so that its left standing.
