Herma is a grotesquely large and overweight hippo with a rough gray coat and blue eyes curtained by long feminine eyelashes.
Much like her huge exterior, Herma is overbearing and likes to have her way. Selfish in the ways of sharing, Herma cares little for the needs of others, ready to satisfy her own desires in the wake of their complaints.
When Herma begins to hog a mud hole, driving away her fellow hippos, Zazu is called in to fix the matter. Though the hornbill attempts to reason with Herma, she viciously abuses him, leading Zazu to call in the other hippos to help make the mud hole bigger. Together, the herd does so, and Herma can no longer hog the entire pool of mud.
