Animal train

The kids I nanny for wrote a story called the Raccoon-O Train. I am about to leave my job and thought it would be fun to have someone draw a picture of the train for them. I would love an image that I could put on a tshirt or something for them. I don’t even know if this is possible - just reaching out for ideas/prices. I was thinking a train that says Raccoon-O Train in the side. With a raccoon driver in the window, and other animals throughout the train. I can look back at the story for other animals. I know for sure- squirrel, cat, a pink fox… it could be cartoonish. I’m up for ideas!
