"Not a lot yet, but it seems to stress the Yeti out less when I take the sleigh instead of flying off on my own," Cassie says, cracking the reigns over the backs of the reindeer. "Yahh!"

'On Dasher, on Dancer' isn't necessary to get things moving, but boy do these reindeer move. Cassie's not the speed-junkie Bart is (no one could be), but she does get a bit of a kick out of being in charge of the flight. They take off almost fast enough to leave the jingling sound of the bells on the harnesses behind.
