[... ahh, it's a uh. Blue pony. Okay. Still, you can't look a gift horse in the- right.]

Speed is good, but can you carry it? Scientifically speaking, I'm not sure your wingspan is enough to carry your own weight-- no offense, much less a bunch of fish. Without special uh, pony powers, are you sure you'll be able to carry a lot?

[But even then. Every little bit helps. So this isn't Sokka turning her down.]
