The Fairly OddParents: Season 1, Episode 7

1 - 7: Father Time

After getting in trouble for melting his father's trophy with heat vision, Timmy wishes for a time-travelling scooter so he can go back in time to stop Dad from ever winning the aforementioned trophy. Unfortunately, Timmy's actions have changed the course of history when he returns to the present: Dad rules all of Dimmsdale, and Cosmo and Wanda never even met Timmy. Now, Timmy must go back to the past again to correct the damage he did to the timeline.
