The Pico

 Rattus Piconicus

A type of rodent with hematophagous habits, this large rat was only identified at the end of the 19th century (when the first Pico was created by Oliver Hofmeier). In addition to the blood of other animals, it is strongly attracted to the sap of some roots. Particularly the Mandragora Forgotteniensis. Jimmy Larson also owned one as a child, indicating they were viewed as an equivalent to hamsters or other pet rodents at that point.
