The white and gray ones are as big as they'll get (barring a change in the game code-- which is under discussion, as I understand it). The purple one grew up, too, but I don't think I should put them all in the sig line. I'm not sure what's up with the green one. It's been stuck at the same state for quite a while now. It's not getting sick, though, either, so I guess it's all good.
