Not enough stars

PurpleSimulation: You must leave this place at once. My symbol is not yours for the taking. Even if you managed to collect, say, 18 stars, you would accomplish nothing. You would only face my wrath. Now leave.

Enough stars

PurpleSimulation: No... You were foolish enough to actually go out and collect 18 stars? You might be able to fool everyone else, but you cannot fool me. I've seen what you've done. I know what you really are. Leave this place, or I shall have to resort to violent measures. Will you obey this simple command?

Fine, I'll leave/I won't leave

Answering 'Fine, I'll leave'

PurpleSimulation: Seems like you're able to use your brain after all.

Answering 'I won't leave'

PurpleSimulation: Then your foolishness knows no bounds. Prepare to face my wrath.

Pre-boss battle

PurpleSimulation: Did you not hear me the first time? BEGONE.

PurpleSimulation: ...............

PurpleSimulation: If that is the way you wish to do things, so be it. I must be the one to dig your grave for you.

Completing challenge

PurpleSimulation: You...

PurpleSimulation: You think you're something special, don't you? You're nothing but a fool.

Returning after winning

PurpleSimulation: I must apologize for the way I acted earlier... I was so caught up in my own anger, though I'm not even sure why... Regardless of what happened, I hope we can make amends.

PurpleSimulation: So... why did you come back to Sandbrick Sandbox of all places? Did you want to try my challenge level again?

Yes/No thanks

Answering 'Yes'

PurpleSimulation: Okay. Let's see if I can get back into character... "You've made a terrible mistake by coming here. Face my endless wrath!"

Answering 'No thanks'

PurpleSimulation: That's fine, I guess... Bye...
