Winnie the Witch — Valerie Thomas

Winnie, the Witch lives in a black house. She has black chairs, black floors and black doors. The trouble is that Winnie's cat, Wilbur, is also black. After sitting on him and tripping over him, Winnie turns Wilbur into a green cat. But then, he goes out into the grass. Winnie is going to need magic to make sure she can always see Wilbur.
