FNAF 3’s troll game had 2 versions, one with the infamous “Trololo” song, originally known as “I am very glad, because I’m finally returning back home” by Eduard Khil. The new version excluded it because of copyright reasons, and was replaced with “Silent Movie - Chase” as it was royalty free. Both of these would play during gameplay. Strangely enough, both versions feature the puppet’s sprites from FNAF 2!
