Moogles cause they kick ass and can dance like no other!
Moombas cause they are fluffy and kitty like and recognize people by the taste of their blood.
Cactaur cause they sport Barber style mustaches and throw needles
Tonberry cause they stab you in the face!!!
Other options like Yeti's and Qu's
None the choicobos games suck but secretly I desire all of them...
