Federati Bigneighbour is the daughter of the Bigneighbour family. She is part of the balloon owner society with Loose, and is considered to be very intelligent.
Her family all have a signet ring that, when all four rings are fit together, form the words “have balloon will travel”.
When seen in America's Playground, she is dressed in a costume for their family portrait: a vicious grizzly bear, mid-kill.
