Hunter: We can't let it get out that we accidentally made a baby.
Tulip: If this baby finds her family, then maybe I can find mine.
Junior: Storks don't deliver babies anymore! If anyone finds out about this, I am dead meat.
Hunter: Junior, I saved this company by getting out of babies and into package delivery. Monday, it'll all be yours, barring some monumental screw-up.
Chosen answer: Hunter had allowed the penguins to take care of the baby, and will then be returned to the human world when she is an adult. The penguins were taking the baby back to their home to raise it.
