Were you looking for the animatronic, Ignited Bonnie?
The Basement appears quite similar to the Attic, as it has a lot of props throughout it. Though, it has some differences. There is some steam, which is both a disability for the player and the Animatronic, as they can't see through the steam. There are lanterns, which glow orange. You shouldn't mistake the light for Ignited Bonnie's pupils.
You are given 60 seconds (1 minute) to complete your objective; to search and find 5 objects throughout the basement.
While you are searching for the objects, Ignited Bonnie will be roaming the layout of the basement and he is slightly faster than Ignited Freddy. To survive being attacked you should keep your eyes on red lights, as they are Ignited Bonnie's pupils. When you see the lights bobbing up and down, it is advised to run away to keep searching for the objects.
