A Habbo baby is a type of avatar users can make in Habbo. Mainly to pretend themselves as babies, they have become targets of insults due to the fact "mature" users believe these people have no lives. The typical baby's characteristic is to use other Habbos for their furniture.
Users have token to uploading videos onto Youtube and exposing the babies, stirring more ridicule.
They tend to believe they can hit or crawl in Habbo and whatever other Habbos say to them, and have been known to cry, spamming it over and over until a willing adopter will talk to them.

People have begun to "hunt" babies to ridicule them or "kill" them to see how they respond.
