I haven't played the game myself but apparently it's quite good. The rank of 17 is called Minus World, which is a secret level in the original super mario bros. Heres some pictures:

 Anyway I managed to acheive Convivial (twenty-one friends):

Smashing good company.
Convivial members of the community are friends to many others--no doubt, many others who are every bit as convivial as themselves! Indeed, such fine company these chaps and gentle-women truly are! Their company is often desirable and often available, and, being such convivial sorts, they are always looking to broaden their horizons by meeting more and more friends, colleagues, and associates. Why, you'd certainly invite them over for tea if you liked tea and knew where they lived. I want to acheive popular but that will take alot of work (is it 60+ friends?).

And I got this:

MORTAAAAALLLLL KOMBAAAAAAAATTT!
