Moppie is Uma's best friend from preschool. Like Uma, she is outgoing and confident. However, she can get apprehensive and scared more easily than Uma. She is generally upbeat and her favorite activity is drawing portraits of her classmates. Moppie and Oobi both regularly visit the same pediatrician, Dr. Rose.
Moppie has fair skin and green eyes. She wears a curly red wig. Four fingers act as her upper lip while her thumb acts as her lower lip. Her fingers are usually curled in a fist-like position.
