Mabel Licorice is one of the residents at Foster's. She appears in most of the episodes as a background character. She appears to resemble a bear-demon hybrid with red fur and a pink body, black wings, large, innocent, baby-like eyes, and wearing a white heart shirt.
Mabel has a sarcastic tone to her. She always has something witty to say; she also tends to have an attitude. Her time at Foster's has made her soft, but she still tends to give off smart remarks. She also seems to quite jump rope really well, as seen in "Big Fat Awesome House Party".
