yup, you basically answered it, except maybe he hasn't beaten all the cups in the oympus coliseum...i think the prize for gaining the hades cup is the yellow trinity (correct me if im wrong pls.)...so, you get the trinity, you unlock the door with BOTH the dalmatians and the aero upgrade, and then get the 99 dalmatian puppies and receive the next spell upgrade...
