Strong-willed and courageous, Juniper is Patchi's childhood friend turned love interest. As a kid, she enjoys playing with Patchi, but although she loves him, she can't always show it. Juniper always listens to her mother and obeys her, although she wants to choose her own mate instead of being part of the herd leader's harem.
Years later when Patchi's older brother Scowler becomes leader of the herd, he chooses Juniper to be his mate much to Patchi's dismay. When Scowler takes the herd across a frozen lake, it starts to break but luckily Juniper along with Patchi are able to get most of the herd to safety leaving an angry Scowler and a few other herd members on the other side of the lake. Later, Scowler confronts Patchi for supposedly trying to take over as leader of the herd and attempting to take Juniper from him, before the two brothers battle for leadership where Scowler wins and disowns Patchi before making Juniper and the rest of the herd leave with him.
Patchi returns later and Juniper plays a big part in helping her friend defeat the wicked dinosaur Gorgon. After this, Scowler allows Patchi to be leader and let's Juniper be his mate where they have eggs. When one of the eggs hatch, Alex asks if the hatchling can be called Alex Jr..
