I need a cartoon with a mascot

We have a shop that sells off-road vehicles, like Polaris rzr, etc, called Fatty’s UTV. We need a mascot. The first tshirt we want would be our mascot (probably a plump person) in an outrageous off-road vehicle, holding a large (fatty) rolled marj doobie. And wording that says “Fatty’s keep the good times rolling”
