Kristen’s parents just can’t seem to do anything right. First they have their baby at the zoo, not in a hospital. Then, they accidentally bring home an baby alligator instead! After it bites everyone on the nose, they return to the zoo and come back with a baby seal! Kristen sees that she will have to solve this problem herself. She bikes to the zoo and finds their baby with . . . a gorilla mommy. When the baby bites the gorilla on the nose, Kristen sees her chance–and takes home her new baby brother!
