“This mysterious endoskeleton will appear at random when closing your monitor. If he is in your office, open your monitor again to make him disappear.”
Yenndo is a Funtime endoskeleton and a minor antagonist from Five Nights at Freddy's: Sister Location. Despite his small role in the main game, he also appears in the Custom Night. Yenndo is an endoskeleton strongly similar to Funtime Freddy's.
So far, Yenndo has only appeared in Five Nights at Freddy's: Sister Location and hasn't been in any game since his debut.
Yenndo is very similar to Funtime Freddy's endoskeleton (whose full body can be seen more clearly from the "Making of Freddy" section in the Extra menu), with complete lack of a suit-shell, to reveal very detailed endoskeleton wirings, somewhat resembling human muscle layers, although, he has three differences - a lack of inner face-plates, both hands (while lacking a hand-puppet), and yellow irises (rather than Funtime Freddy's hazel/blue). If observed closely, his nose looks different compared to Funtime Freddy's, being slightly flatter. Yenndo doesn't seem to wear a hat, nor hold any form of microphone, though, he does appear to have an upside-down screw at the top of his head. This screw could be reminiscent of a hat.
Unlike Funtime Freddy's own endoskeleton, Yenndo's appearance somewhat resembles that of a human, despite his similarity to one of Funtime Freddy's images from the "Making of Freddy" section in the Extra menu, where his full, visible endoskeleton is shown.
