This is a minor cutscene.
After beating Level A-9, a cutscene will begin in which the Pastafarian invites the Student to come to a party. The Student declines because she isn't in the mood for a party and she has to run tests. The Pastafarian presses her again, telling the Student that the Flying Spaghetti Monster is coming too.
The Student seems to reconsider at hearing this, excited by the prospect of meeting the Flying Spaghetti Monster. However, when the Pastafarian informs her that "He'll be invisible and intangible, as usual," the Student politely refuses again and continues to run tests. The Pastafarian expresses concern for the Student, as she is worried that she spends too much time alone, but the Student insists that she is happy doing her experiments.
If you look carefully, you can find the Child hiding on the background of this cutscene.If you pay attention to the Pastafarian in the final frame, you will realize that her wooden spoon has disappeared.
