Blooper Baby

Blooper Babies, also written as Bloober babies, are infant Bloopers. In most of their appearances they are often seen alongside Blooper Nannies, a species of female Bloopers who release multiple Blooper Babies when they glow, afterwards Blooper Babies will follow their mother and help her pursue Mario.
