| This level is a major plot point!
This level is a major level in the game. After you finish the level, you may be able to access other characters, minigames, and tunnels. Most of them also include a cutscene.
However, you can still use the Runner, and they play very similar, so the gameplay for both characters is the same. Just find a route that works for you and follow it. It shouldn't be too hard.
The Bunny works as well. You can hop your way to the end of the level. If there is no path in front of you, you could always hit the side of the box and land somewhere.
There is a cutscene that featured in this level. More information on this cutscene can be found here.

After beating 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.
