Weasel is a weasel who makes the journey from Farthing Wood to White Deer Park in both the books and the TV series. Weasel is male in the books but is female in the TV series. In the books, Weasel is a respected senior member of the group but in the TV series, her character is changed to a silly, immature creature who often gets on the other animal`s nerves. Weasel is also larger in the TV series, resembling a stoat.
Deep down inside, she is shown to be helpful and respectful and really does care for those in need.
She becomes Measley's mate in season 2, although she never returns the affection to him, she deeply does love him so. She also loves her two children dearly and would never let anyone hurt them.
Weasel is very emotional and territorial as weasels are. She also shows great concern for those when they have helped her.
