Let's track down the Poppy Playtime Imposter who's been hiding in our midst!
Of course, the impersonator is you, Huggy Wuggy, who uses the mouse to navigate the spaceship. When the crew members are completing their allotted work and no one can see you, go behind them and hit the kill button to kill them. When you have eliminated all of them, the level is completed.
Make sure you don't get caught by them, for if you do, you'll be removed from the spaceship, as is the case with all found impostors, and you'll have to start over. Good luck, and revel in the fact that you are able to be here!
