Funny you should say that, this is an old design but when I was rethinking the game lately and designing new characters themed karts came to mind.  That one specifically :p I definitely want to incorporate that now.

 scuba diver because of the pun of scuba driver, originally thought up for a game I wanted to do.

Thanks for the constructive criticism it's taken into account :P

i personally love this type of art, and as for the game, it was very fun...until i accidently clicked a link on my browser ;_;
