"Futurama is an Emmy Award-winning animated American sitcom created by Matt Groening, and developed by Groening and David X. Cohen for the Fox network. The series follows the adventures of a former New York City pizza delivery boy Philip J. Fry after he is frozen, seconds after the start of a new millennium, on January 1, 2000 and is revived one thousand years in the future.

Lead character Philip J. Fry is an immature, slovenly pizza delivery boy who is frozen just after midnight on January 1, 2000, reawakening on New Year's Eve, 2999. He gets a job as a cargo delivery boy at Planet Express, a company owned by his closest living relative, Professor Hubert J. Farnsworth.

The Scooty-Puff Jr appears in "The Why of Fry" the tenth episode in the fourth season.

Leela and Bender go on a mission without Fry, and he feels dejected and unimportant. That night, Leela is going on a date with the mayor's aide and asks Fry to take Nibbler for a walk. She meets him in a bar on her date, which is going very well, as she is impressed by the aide's power, which makes Fry feel even less important. He tells Nibbler that at least he is important to him, and Nibbler talks to him, telling him that he is indeed very important. He knocks him unconcious and takes him to the Nibblonian planet.

A group of elders tell him that he is the most important person in the world because, as he is his own grandfather, he lacks the delta brainwave, making him immune to brain aliens. The brain aliens are trying to collect all the information in the universe, then destroy it to prevent new information arising. Fry must infiltrate the brains' database on a Scooty Puff Jr -a wind up short-range single-person spacecraft intended for children and plant a bomb that will suck it into another dimension. The database tells him that Nibbler actually planned and caused his freezing in 1999, and is very upset. Riding the Scooty Puff Jr braks, and Fry goes into the dimension. The brains allow him to back in time to 1999.

He catches Nibbler, but, as the fate of the universe depends on it, and he wants to save Leela, he makes himself get frozen, and tells Nibbler that Scooty Puff Jr. "suuuuucks" before he disappears.

Back in the future, Fry escapes the bomb on his improved scooty puff Sr ( the "doom bringer"). and Nibbler wipes his memory."
