In the original Crash Team Racing for the first PlayStation released in 1999, Komodo Joe's in-game driver model has buck teeth instead of his usual fangs, and poor Joe sure looks like a nerdy freak, even his brother Moe was shocked about this.
Mainly because models in certain PS1 Crash games have different models every time, like in CTR where they are different than one another, but in Crash Team Racing: Nitro-Fueled, they're using same models in racing, podiums, and cutscenes, so Joey won't be having buck teeth in racing. ^^
