Hard question. Numbuh 4 is adorble in a little brotherly way, Numbuh 3 is SO cute, Numbuh 5 is pretty in her own way, and Numbuh 2 is so... well, आप know what I'm gonna say. Not sure what to say with Numbuh 1, though, even though he is mega cool.
I think Wally is the hottest. I also think the way that Hoagie is intelligent and that he makes alot of the 2X4 technology is awesome, but when he hits on Cree, I think is gross, and I प्यार Nigel's leadership and English accent :) Numbah 5 is pretty and so is numbah 3 (kinda) but i dont really like numbah 3 that much
