History Trivia / SonicUnderground

* CrossDressingVoices: Jaleel White as Sonia. Oddly though, if one watches an episode of ''Sonic Underground'', you can tell the voice Jaleel White uses when providing the voice of Sonia sounds inconspicuously identical to the high-pitched voice White used from his other (more) famous role as [[FamilyMatters Steve Urkel]].

It's Creator/GaryChalk, aka [[WesternAnimation/BeastWars Optimus Primal]] and [[AdventuresOfSonicTheHedgehog Grounder]]! Actually, Jaleel White, who plays all three siblings, has said that he uses his Urkel voice for Sonia.
