Willow is a dark blue bird that is female. There will be no information about Willow until Angry Birds Stella is released(except that she is one of Stella's friends). She has 6 pieces of long hair and likes to play with the others, because it shows her pulling the tail of Stella in the character sketches. She does not seem to be much of a daredevil, as she seems shocked as Luca approaches the edge of a tree branch in the cover art for Angry Birds Stella. She loves to have fun, be adventurous, and be creative like the rest of her friends.
Willow is very artistic and loves to daydream. Unfortunately she has grand ideas but cannot always follow through. It aggrovates her to see someone destroying her habitat. She is a free spirit but is the shyest of the group. She also feels safest when wearing a large, oversized hat. She sometimes holds back her feelings aside from when pigs are around. She hates it when someone disturbs her when she has a creative art session.
