When the Cookies are baked, one can choose a hiding place, no matter how safe it is, the cookie thief finds the sweet joy.
No matter whether you choose a kitchen hiding place, put the cookies in the bank vault or attach a bicycle lock to the cookie jar, it's all futile.
When it is night or nobody is at home, the cookie thief sneaks out of his hiding place into the warm room and organizes a cookie feast.
His seventh sense is sharpened on the jam and powdered sugar. Once the cookies are baked and the smell is in the house, there is no going back.
Or who else could it have been? It must have been the crocodile.
