|Full name:||Madder Foxgloves|
|Species:||Red fox (Vulpes vulpes)|
|First Appearance:||Vulpes et salsicia|
Madder is shown to be a fox with a light ginger pelt. He wears a red poncho with blue and beige stripes. The poncho also happens to have eyes, which seem to show emotion as well. These expressions usually differ from that of Madder's, meaning the poncho probably is an entity on its own. Madder does not have any arms, but will receive them once he has shown he can be a good person.
Fustic is Madder's cousin. The relationship between the two is unknown.
