Give your best impression of Mangle & their fixed counterpart (preferably with an added-on filter). His voice and mannerisms should be similar to those seen in his appearance in FNAF AR. When doing Mangle, try to sound more raspy and bitter, and pretend you're struggling to say your lines due to your broken voice box, like in the games.

For her lines, do two different voices on top of one another (like in FNAF AR); one sounding more feminine and one sounding more masculine

Perform each line read once as Mangle and once as Funtime Foxy (Fixed Mangle; not to be confused with Funtime Foxy from SL)
