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!
