Hey guys...maybe you can help me...I remember reading a children's book, many years ago when I was still in elementary school. I can't remember the title, but let's see if I could describe what I remember.

-It was a family barbecue (I think)
-The son finds a strange house in the woods that has cookies shaped like animals
-The family eats said cookies and turn into said animals
-I think there was a wizard involved who made the cookies in the first place.

I've been racking my brain trying to find that old story...if any of you know what I'm talking about I'd be forever indebted to you.
