Stuart Stone was the voice of Ralphie Tennelli in the animated children's series The Magic School Bus.

Stuart was born on November 17, 1977 in Toronto, Ontario, Canada.


  • In the 1st season, Stuart's voice for Ralphie was appropriate for a kid who's supposedly 8-9. In Season 2, Stuart's Ralphie voice was noticeably getting a bit deeper, and in Seasons 3 and 4, Stuart's voice for Ralphie was very teenager-like. The reason for this is because Stuart was going through puberty at the time.
