Best nanny contest

As Miss Moon sits down on a bench at the playground, the nanny Miss Bunch reacts very annoyed, as she claims this for herself. She challenges Miss Moon: if she wants to earn the right to continue bringing Baby Joe to this playground, she has to face the nanny competition. If she loses, it says goodbye bank. Should she win, the bank is hers. The magical nanny faces the challenge, but quickly realizes that Miss Bunch is a very strong opponent. A bit too strong for Miss Moon's concepts. Is that right thing?
