[Dylas jumps at the sound of the whistle; he'd been too busy hating his introduction to desert life to notice Urbosa straightening up or preparing the next step of what is apparently the worst trip he's ever been on (no fault of hers, of course). He hears the bark immediately, his ears perking up and in that direction.]

...Are you saying you ride dogs? Wait.

[He has to wipe the sweat out of his eyes (again) but when he refocuses his vision, he clearly sees something that isn't a dog running towards him at full speed. Running? Flopping? What is this thing, he's never seen anything like it before.]

We're both going to ride that thing? Don't...don't tell me, it grows or something? There's no way either of us would fit.

[Dylas is over six feet tall himself, the most horse-like beanpole. He stares up at Urbosa with the most stupid, most confused look on his face.]
