The booklet begins with a strip in which Charlie Brown tests his sister, Sally to see if she has "lazy eye". Sally is told by her opthalmologist that she has to wear an eye patch for six months. Sally faces some taunting for wearing the eye patch, she also has trouble finding it because Snoopy takes it to play pirates. However, she enjoys explaining to the other children why she has to wear it and is happy to hear that her eye condition is improving.
