Yenndo

Yenndo is a mysterious endoskeleton character from Five Nights at Freddy's: Sister Location. Despite having a small role in the main game, it returns as an antagonist in the Custom Night and Help Wanted 2. Yenndo closely resembles Funtime Freddy's endoskeleton but lacks inner faceplates, has two hands instead of one and a hand puppet, and possesses yellow rather than blue or hazel eyes. Yenndo can appear as a rare hallucination in Funtime Auditorium on Night 3 of Sister Location. In the Custom Night, it randomly appears in the office like Golden Freddy, rapidly depleting oxygen, and players must open the monitor to make it disappear. In Help Wanted 2, Yenndo takes over Funtime Freddy's role in Breaker Room: Hard Reset. Yenndo's name might be a portmanteau of 'Yellow Endo,' because of its yellow eyes. It is distinguished by the absence of a hat and microphone, and as the only Freddy counterpart with a fully visible endoskeleton. Yenndo's behavior is a combination of Golden Freddy's from Five Nights at Freddy's and Five Nights at Freddy's 2. Additionally, it's the only endoskeleton in the series with a confirmed gender.
