IN LEVELS

Cortex: "Meet me on level B, I have something to show you."
A voiceline in most Iceberg Lab chunks. Most likely a way for Cortex to tease Crash just before the Psychetron, judging by how proud he is of it in the cutscene.

Cortex: "Spin me if you like, but I'll never give up my crystal!"
A voiceline placed in several Cavern Catastrophe chunks.

Cortex: "The doors! Close them! Quickly!"
A voiceline in the ant drill fight chunk in Cavern Catastrophe. Most likely for the end of the drill's first cutscene.

Cortex: "Naughty dog, naughty dog!"
Scrapped voiceline meant to be used with Cavern Catastrophe Rollerbrawl idle animations.

Cortex: "Surprised to see me, Crash?"
Leftover from the demo's short version of the Cortex boss intro.

Some of the lines were localized in the PAL and NTSC-J versions:

Voiceline	French	German	Italian	Spanish	Japanese
Now be careful...

Spin me if you like...
The doors...
Naughty dog...
Surprised to see me...
