Yolanda Hall (PPR)

Prehistoric Park's assistant veterinarian, Yolanda Hall is easy to like; she's bright, outgoing, likes to make jokes, and is fiercely loyal to her friends. In particular, she is close friends with Leon, Adrian, shares a lot of common interests with them, and spends almost all her time with them (when she isn't either distracted with her work or forced to wait for Leon and Adrian to come back from work or missions alongside Drew).

Yolanda and Jack share a similar sense of humor and are very good friends; Jack has even called her his best friend.

However, she can also be a bit of a spitfire, and only allows Adrian and Leon to call her YOLO-Girl and get away with it without a punch in the face (for girls) or kick in the balls (for guys).
