Yolanda likes to yell, scream, talk loud and yodel a lot while standing on her pet yak who's yawning. In the Living Books version, she's very excited yet tired as well as her yak is. She likes to ride the humps that the Yak pops up on his back and enjoys pulling his tail at times even pulling and rolling his fur.
