You Can't Judge a Girl by Her Limo - S1.E3

When the new girl, Sarah Witney arrives at Horseland, Chloe and Zoey are eager to meet a fellow wealthy girl. However, Sarah just wants to make friends with the nice people (and horses) of Horseland, and so does her horse, Scarlet. The rest of the gang judge Sarah before they meet her because she's rich, after which Sarah decides that maybe she just doesn't belong at Horseland. Eventually, the others decide to give her a chance and everyone becomes good friends.
