BibyBab's are seven human-like animatronic's with a round body, peach-colored skin, large blue eyes, a human-like nose, and a toothy grin. All seven versions of BibyBab's are notably some of the smallest animatronics in the series.
- BidyBab and Minireena are the only known Animatronic's not part of The Birthday Party Schedule
- There is a possibility that the voice in the trailer was the BidyBab's instead of Circus Baby herself.
- Bidybab is an anagram of "Baby Dib"
