The Worst Witch

A 1001 CBYMRBYGU. At Miss Cackle's Academy for Witches, there are many witches, but no one is as terrible at witchcraft than Mildred. She goofs up every spell she attempts. Poor Mildred is always in trouble.

...the girls marched up in single file to receive their kittens. Mildred was the last of all, and when she reached the table Miss Cackle pulled out of the basket not a sleek black kitten like all the others but a little tabby with white paws and the sort of fur that looked as if it had been out all night in a gale.

“We ran out of black ones,” explained Miss Cackle with a pleasant grin.

Miss Hardbroom smiled too, but nastily.
