When Grandmother Pig comes for a visit, Oliver and Amanda learn just how much fun it is to have a grandmother in the house.

Amanda Pig may be the youngest in her family, but she's growing up. She's big enough to care for her stuffed-animal babies, and she's big enough to help Oliver make a bubble bath. But is she too big to snuggle with Sallie Rabbit?

Amanda wants to do everything her big brother, Oliver, does. She wants to run as fast and jump as high, but it seems she never can. Is there anything Amanda can do as well as Oliver?

Poor Amanda Pig! She's never going to get any sleep with all of the monsters in her room. Or maybe there are no such things as monsters. One thing's for sure, though: Amanda is going to have to be a big girl if she wants the monsters to go away for good.
