A children’s book with stories about witches & wizards from the late 80s/early 90s.

The book had colourful illustrations; one witch had striped leggings & funky punk clothing/ hair.

One story was about witch baking special muffins that turned a girl into a goblin to make friends.

Update . . . . . .

I think I mixed up a couple of stories from that book I had wanted to be found… I believe the good witch in that particular children’s book actually gives her neighbour-girl a hat that turns her into monster to make friends with the other little monsters that also live around the area… I hope you can find this book… I’ve been trying to search for it for many years.
