FNAF 2 "Double Trouble" Custom Night Tutorial!

Five Nights at Freddy's 2 has a custom night challenge called "Double Trouble". Here is a strategy to help you beat it. The Strategy:
1: Flash your flashlight down the hall. If Foxy is there, flash your flashlight 3-4 times. If Bonnie is there, don't do anything and just wait for him to leave the hall. Once he leaves he will first go to Party Room 1, then enter the Left Air Vent, and last come into your office. Immediatley put on your Freddy Fazbear mask, or you will die.
2: Check the Right Air Vent Light. If Toy Bonnie is there, put on your Freddy Fazbear mask and wait for either the vent sound (mobile) or his head flashing across the screen (PC).
3: Repeat steps 1 and 2.
As a prize you will get a little Old Bonnie plush on your desk in your office.
