It's rare that Toph goes anywhere by herself. It's not too hard to tell that she's blind; considering she moves slowly and generally has a hand against whatever wall or rail is available.

What isn't immediately obvious is that she's normally relatively belligerent and combative. If Toph bumps into you, or winds up somewhere that's not near food or a lounge chair, she'll pipe up with a squeaked "Sorry! I'm having a little trouble, here," or a practiced "Gosh, guess I got kinda lost again!"

But she may not always show that she's almost always distressed: wisecracks in place of a sometimes stubborn pout set into her face. At least the rails and piecemeal parts of the ship that are metal provide some amount of comfort, though it's certainly not enough to calm her down completely.

"Stupid oceans. Stupid ships. Stupid kidnappings!" Where's her Zuko-shaped taxi when she needs him? Probably off stuttering somewhere...
