If you realllllllly want to dissect this (because I'm a loser) In the early Lazytown plays, Sportacus mentions that he eats fish and other meats, as well as vegetables. I think they just make it all about the ✧・ﾟ: *✧F R U I T✧・ﾟ: *✧ to make it easier for kids to understand. That said, he eats like a normal, healthy human being. Apparently this is oppressive. Fatties gonna fat.
