I am still kind of split opinion with this. I mean, on one hand, the Kikwis were so AWESOME, but then the mogmas were really helpful and very productive, IMO. But I think the Kikwis win this one out...
The mogmas were my favorite new race. Too bad they most likely went extinct later in the timeline. The Kikwis were enjoyable too. The Parella didn't do anything though.
i Dislike the robots, so i hope they do not come back. other than that anything is fair game. but the the one i want most ( i dont know if this even counts ) are the loftwings
