It just dawned on me recently that in TPM, Anakin isn't in a real race, he's in a kiddie joke race. That's the only explanation I can think of for why EVERY racer is a little person. How do you explain Mawhonic, who is supposed to be an adult Gran and yet is only slightly taller than a 9-year-old? It's a "freak show" race, pure and simple, the people of Mos Espa are secretly laughing at the racers, most of whom are height-challenged, and Teemto Pagalies is mentally handicapped. The whole thing is probably bankrolled by Ben Quadinaros who knows this is the only way anybody will let him race, that's why his is the only podracer with 4 engines, and even then he screws it up!
It's cruel and it's sick.
