Rasha is a young rhino with long lashes and blue eyes. Her skin is tan, tinged brown, and her horns are ivory.
When Zazu is arranging mates for every animal in the Pride Lands, Rasha weeps about how lonely she is, as she is without a love interest. Seeing her in distress, Zazu tries to comfort her, but Rasha sees his kindness as an act of love. Delighted, the rhino pursues him as a mate, chasing him across the Pride Lands while cooing lovingly to him.
In the midst of the chase, Zazu runs into a nervous young rhinoceros named Kuloo and arranges for him to hide behind a tree. When Rasha draws near, Zazu calls for her, and she runs her horn through the tree, colliding with Kuloo. Upon seeing each other, the rhinoceroses become immediately smitten, and Zazu is saved from Rasha's fiery affections.
