I will keep those names in mindPersonally, I think Runway is a great one. Jet (stream) would work for the darkest one.... Turbo (for Turbulence), Prop (peller for the talkative one), Aero (naught), with Cockpit for a roo (yes, good idea).
Alex, if he does like last time, will get to know the littles before he give away ANY of his name ideas.
