Any explanation on why thera was no Rocko's Modern Life representation on Nicktoons Racing (1999)?
With the other shows there are at least a excuse: Doug is owned by Disney, Rocket Power was new at the time and it would be out-of-character seeing them riding karts instead of skateboards and rollers, Kablam! would be and it's still a heck to license (even if it's just Henry and June), and Oh Yeah! Cartoons is Oh Yeah! Cartoons.
