I considered "aberration" in a couple different ways. Thinking about narrative aberration, I remembered Kafka's Metamorphosis, in which the protagonist wakes up and discovers he's a giant bug.
In Norm's Face, Norm wakes up and can't find his face.
There is also a game play aberration, which I won't share in detail here for spoiler reasons. Broadly speaking, well established expectations of game play will not get the player to Norm's face.
