Revenge of the Small Small OP

Patsy Small is the youngest in her family, and she doesn't like it one bit. Her older brothers and sister are always teasing her. Even when they come down with the chicken pox, they don't appreciate everything she does for them.

Then, after they all get better, Patsy herself gets chicken pox. Her father brings home something just for her to play with, but the older kids try to ruin it for her - until Patsy plans a little revenge of her own. All ends happily, however, when the bigger Smalls repent.
