Best friends Mary Anne and Dawn are ecstatic to discover that Dawn's mother and Mary Anne's father are planning to get married.

Claudia begins to think she might be adopted when she notices there are hardly any baby pictures of herself in the family photo album and she can't find her birth certificate or birth announcement in the newspaper.

The Baby-sitters investigate terrible noises coming from the old Hennessey place, which is sitting on top of a graveyard and may be haunted.

Karen has to get glasses! She doesn't want them, especially because school pictures are going to be taken soon. But she picks out some pretty pink ones and thinks she looks very grown-up. Then Yicky Ricky at school starts calling her names, like Owl Girl and Googly Eyes. If Karen wears her glasses for the school picture, Ricky will make fun of her. If she doesn't wear them, she'll feel like she's afraid to be herself. Glasses or no glasses,...

It's going to be a great weekend! Karen has new roller skates and is a very good skater. She's looking forward to trying some new tricks. But, oh no! Karen falls down and has to go to the hospital. Her wrist is broken! Karen is determined to get everyone she knows -- plus someone famous -- to sign her cast. It isn't going to be easy, but she won't give up until the job is done.

While baby-sitting for practical joker Betsy Sobak, Claudia breaks her leg as a result of one of Betsy's pranks and wants to quit the club, prompting Kristy and the other baby-sitters to teach Betsy a lesson.

Claudia oversteps her bounds when she spends all her free time with her aunt's new baby and monopolizes the baby for herself.

Karen thinks her next door neighbor is a witch, and wonders if the witch will cast a spell on her. Or is she brave enough to send her and her friends away?
