Plupp is the protagonist of a series of
children's books by
Swedish author
Inga Borg (1925–2017),[1] who first created the character in 1955. Plupp is a small figure with blue hair and a red nose, who lives in a kåta by a lake called Blåvattnet ("Blue Waters") somewhere in the
far north.[2]
Borg describes the character as an invisibling (meaning that Plupp is invisible to humans) who is both human and animal in nature.[3] She further explains that Plupp is neither male nor female, as she wanted to create a character that children of both sexes could identify with. Plupp also has the ability to talk with animals; two of their closest friends are the
lemming Lämmel and the
stoat Hermelin.
