Okay, so I posted on a different thread that Frankie Muniz voiced a zebra in the movie "Racing Stripes". He and Justin Berfield have also provided their voices for characters in Fairly Odd Parents, a Nickelodeon cartoon or Kim Possible, a Disney cartoon. Muniz voiced Chester McBadbat from 2001-2003 (Guess he was busy with MITM?) and Justin voiced Ving in a 2004 episode of the Fairly Odd Parents. Chester: http://www.youtube.com/watch?v=gFxtBZfa16M You can hear Frankie on 1:03
I couldn't find Justin's work, but if you want to try and find it yourself, you might want to know when the episode aired and what it's called. June 2004, Season 4 Episode 8 'Crash Nebula'.
As for Kim Possible, Justin Berfield also provided his voice there for a character named Gill (Now you know how I got my name ;..also because I had an obsession with fish-related names then) He's been in 2 episodes from 2002-2004. http://www.youtube.com/watch?v=svlwf...eature=related Gill appears in the beginning, but doesn't actually start talking until :30, but he only says "Give it up, Ronny!". He says more at 2:34 though.
