What's Wrong With Daddy?

Bibi Blocksberg's father, Bernhard, has never been fond of magic or witchcraft. So when he suddenly decides to become a witch, Bibi and her mom, Barbara are more than a little surprised!
First, Bernhard tries copying his daughter and wife when they cast spells, but that doesn't help. He then follows Bibi to school and embarrasses himself in front of all Bibi's friends. Something is certainly wrong with Bernhard…
Will Bibi be able to get him back to normal again?
