Although her name is "Calico Woman" all throughout the episode, the end credits say "Calico Girl".
During the chase everyone runs down the street, then when Justin and Max come out onto the street, they run right back the way they came, even though presumably they haven't turned around.
At the end of the chase, when Riley and Alex pull up to the dunk tank, Calico Woman can be seen in the background casually standing around by a lamp post, even though she's supposed to be chasing after them. After Alex tells Riley that jealousy on him is so hot, Calico Woman can be seen starting to run, as if given the cue to do so.
