what do you mean by Julie and Vleugel are "wingless"
Vleugel is Wingless, he misses a part of his left wing. With all the running around he got athlete legs. One time when he tried to fly and he made a salto and landed on his face. Ouch!
Julie loves to fly, maybe she is too wild for him.
I'm not so good with duck names so I name them after their handicap if they have one.
