Freddy.

Freddy is a brown-colored bear animatronic with blue eyes and appears as a smaller version of himself from the  Five Nights at Freddy's  series. He wears two black buttons and a top hat. He also carries a microphone in his right hand.
 * In Dee Dee's minigame, Freddy is only one who is available to be on a boat just like in overworld.
 * Freddy has more counterparts than any character in the game, totaling 13 (18 if the enemies are counted).
 * Freddy in FNaF World wears buttons while himself from the first Five Nights at Freddy's game doesn't.
 * Another difference is that he is missing the whiskers on his muzzle.
 * Another difference is that Freddy has upper teeth.
 * Oddly, Withered Freddy from the core series has nearly the same appearance as Freddy, but with different skin, eyes, microphone and broken parts.
 * If the player clicks on Freddy's nose while in the title screen, it makes a honking sound, similar to doing the same in various locations of the Five Nights at Freddy's series.
 * Freddy is the only character the player can play as in the Overworld, even if he isn't in their party.
 * Freddy doesn't have black rings around his eyes, unlike in Five Nights at Freddy's. This applies to every animatronic.
 * In fact, those black rings are empty spaces in the mask of the character's suit, where the animatronic's endoskeleton can sometimes be seen.
 * It seems that Freddy's attack animation is mainly for his "Mic Toss" attack.
 * This can be proven by that Freddy loses his microphone within the animation.
 * However, with "Pizza Wheel", this could be interpreted as Freddy throwing pizza, or possibly directing them.
 * The same goes to Toy Freddy.
